Have at it.

How many times you've tried this ?

I used to play a cold number system, betting 6 to 12 cold numbers.  But, as most experienced players know, cold numbers can stay cold for awhile.  When my number hit, I would now replace that bet with a new cold number.  But most of the time, I realized that after a hit if I would have kept the same bet it usually would hit several more times.

It seems that when numbers or sectors go cold, once they do hit they hit several times in short clusters.  So, the last time I played this way.  But to answer your question, I haven't played this with real money that much.  My last trip I played this way betting the table minimum the whole time ($5).  Made about $600 in a couple hours.  So will probably play again next time
