Quote VB Meister tor 19 apr 2012 from other forum ...

Some people dismiss factors like altitude, barometric pressure etc.
Although I believe the moon also has an effect look at spring tide during full moon.
High and low pressure systems rotate ccw in the Southern Hemisphere and cw in the Nothern hemisphere.
Look at water draining from your bath.
Same thing.
Does that have an effect on cw and ccw spins?

I chart barometric pressures when I track and when I play.
Just by doing that, you could be close to 10% better with predictions instead of using static info.

Think of barometric pressure this way.
It is about the resistance in the air.
Same as with altitude.
If you play at sea level, the air density is high.
This causes the ball to travel less distance than at altitude.
Watch a cricket game.
Playing at altitude the ball travels quite a bit further than at sea level.

The above is true for deflector hits but also for scatter.
Especially playing a low fret or scalloped wheel where the ball almost always scatters forward and the forward momentum determines the distance traveled.

Interesting about barometric pressure in casinos and outside casinos.
Seldom I would think there is much difference.
I only take barometric pressure on the day in the casino.
Not outside. 
It makes perfect sense though that the pressure shouls be equal inside and outside.
When I get up in the morning and the air is heavey with moisture, I lick my lips.
There is no doubt the heavier the air the better conditions.

Barometric pressure influences ball scatter, the problem is that you need huge(over 10k) data to analize it.

You should divide BP by day(sometimes half  day), check for chances in the day.

The division can be about every 5 to 7 milibars.

BP do not vary in or out the casino, altitude is the fact that varies it. Test BP in the casino and in a 10th floor.

Differences results are sligh, the edge that we might add is 1 to 3 points.

Most of the cases it takes to add or susbtrac a couple of numbers to the regular play.

Nice intput Toby - i also read that you mention that the distance/yardage can drift due 1k and 5 mb.

EGO, take notice that at the beginning of a day BP could be 1010 and by the evening is 1015. It doesn´t happen so often but you must collect data and input it to thheir separate realm.

Every 5 to 7 milibar separation is the basics.

You must divide hits day by day.

It depends of what kind of AP you are, you´ll see differencies but BP only help and edge.

I´ve never test and analized moon phases and humidity, I really donnot know if they help

One question ...

-

The moisture in the air - degree of water in the air - humidity ...

How do you measuring "relative humidity" what is the unit/sign ? is it just % ?
As for Air pressure its mb= millibars ...

Would we state ... There is no doubt the heavier the air the better conditions.

Straight Facts About Humidity

Humidity is the amount of moisture or water vapour in the air. You, your family, and your pets produce moisture when you breathe or perspire. Even your indoor plants produce moisture. We add water vapour to indoor air through routine household activities: cooking, showering, bathing, doing laundry, and dishwashing. More moisture can enter your home from the surrounding soil through a basement or crawl space.

Relative Humidity

Humidity is normally measured as relative humidity (RH). RH is a percentage that indicates the amount of moisture in the air relative to the maximum amount the air can hold at that temperature. For instance, when air at a given temperature contains all the water vapour it can hold at that temperature, it has a RH of 100 per cent. If the humidity exceeds 100 per cent, moisture will begin to condense from the air. If the air contains only half the water it can hold at that temperature, the RH is 50 per cent.

Warm air can hold more moisture than cool air, so that the RH of a sample of air will change as the temperature changes, even though the actual amount of moisture in the sample air does not. For example, as a sample of air cools the RH rise



Using Your Hygrometer

Your hygrometer will show the relative humidity (RH) in your house. Although the RH will not be exactly the same throughout your home, one hygrometer per house is usually sufficient. You should place it where the humidity symptoms are most obvious, in the room that you are most concerned about, or where your family spends the most time. Because hygrometers are small, they can be moved around in your house from time to time.

Don’t place your hygrometer near a radiator, a heat register or a chimney, or in any other location where it could be affected by direct heat.

Remember that a hygrometer does not produce instant results. It may take up to two hours to provide a stable reading in a new location or to adjust to sudden changes in relative humidity.

Why not use both - Casio Trek watch and Hygrometer - sound pretty cool
Search for Casio Trek watch with air pressure and hydrometer - find some other alternative - but not with measuring air pressure.

There is no doubt the heavier the air the better conditions.

Not really. Technically on most wheels, the scatter would be ever so slightly better when air pressure is higher, but by no noticeable amount. All air pressure should be seen as is "different conditions" that affect the ball deceleration rate and speed at which the ball falls (on average). Most significant is overall deceleration. But ball track grit makes much more of a difference than air pressure.

Some of my players track air pressure and humidity but you dont really need to. They are just a guide. They can tell you when one variable has significantly changed. Its like knowing a potential cause, but you also need to know the effect. It is much better to go directly to understanding and accounting for the the effect. Besides there are so many variables you dont always know which has had which effect.

OMG i search and read before i find the right Casio watch.
I been recommended to get Casio Protrek PRG-250T-7DR ... Titanium

But in Europa the same watch has different name - witch was confusing at the begining of my search - but finally find it ... Casio Protrek PRW-2500-7ER ... Titanium

I find i good price 400 Euro ...



Air pressure
Sea & tide level
Moon phase

There is also the same watch with out being made of titanium ...
Casio Protrek PRW-2500-1ER
For around 320 Euro

Ego, what do you know about humidity, moon phase and their influence in ball orbits?

[ego]

That is private witch i would not share on public boards.
And it not about what i know it is about what i have and seen.

Witch is why i will start to measuring the density in the air and air pressure - also note the sea level and moon phase - is not complex at all - just note values and positions and chart data with does present conditions.

I been speaking some pepole among the Advantage-play community and receive some very nice things - witch become a real eye opener.
For me the effect is not so huge as i only visit my local casino once or twice each week and i have not start traveling.

Sea level & tides has a close relation to gravity and moon phase.
Wheater in general has a close relation towards amount of water in the air and air pressure.

Now i find a watch who almost take all data i need witch been mention above.
I will use two watches at the same time and the missing one is one with hygrometer.
