Theory Test On Double Streets/Lines

[Bettingking]

I have tried this betting progression (5 DStreets) which seems to work well walking away with 15-20% profit for 8 sessions to date:
It may take awhile but who cares!!

+2 on a loss
-1 on a win

As you will realize 2 losses close together will take awhile to catch-up but I have other systems that help with recovery 
I had 4 zeros within 10 spins which doesn't help!

What bankroll recommend ,how many units?

[Proofreaders2000]

Three random triggers work for me atm:

If a dozen misses five consecutive times.

If a column misses five consecutive times.

If any even chance misses four consecutive times.

[RouletteGhost]

One bet after each trigger on the missing?

[Bettingking]

Ozon, I've just tested on 1 unit for initial starting, so 1 unit on each of the 5 double streets not repeated in the 3 row matrix.
I don't go to the casino with anything less than 500, but 250 min. should easily do it.
You could also try staying at 2 units if still not back to original bankroll balance, then back to 1 unit for faster recovery.

One bet after each trigger on the missing?

Correct.

Attached is Spinmaster for tracking dozens and even chances.

If any even chance misses four consecutive times.

You bet that dozen, columb, or EC once when it has not shown
that many times?  Flat?

*Let me try the example again

(My quote)
If a dozen misses five consecutive times.

If a column misses five consecutive times.

If any even chance misses four consecutive times.

If any of the above happens flat-bet all
lines except the 5th newest number's line once.

Example: 34,19,7,8,14,12 (newest spin-value)

High has missed four consecutive times.
Bet all lines except L19-24 once. [One unit per line (5 units)]

[Proofreaders2000]

Update

If a dozen misses six consecutive times.

If a column misses six consecutive times.

If any even chance misses four consecutive times.

Choose two of the three triggers.  Flat-bet all
lines except the 5th newest number's line once.

Zeros are ignored during tracking.

[Proofreaders2000]

Update-Only one trigger is necessary

*If a column misses six consecutive times.*

Flat-bet all
lines except the 5th newest number's line once.

Zeros are ignored during tracking.
