System confidence question

At what point (sample size) do you feel confident in a system to start wagering some decent money on it?

I've been running 3 totals parlay systems since Jan. The system progressions are like the one Dan uses in his NHL parlay system. It's eight games and with a starting bet of $5 the progression for the 8 games are $5 $10 $15 $25 $40 $60 $90 $125

My record is:

System 1      100-9 (+$732.86)

System 2      118-13 (+$141.54)

System 3      109-4   (+2598.97)

Over 100 games and I'd run it.

And what's System 3?? lol

@race444

System 1 is both overs/unders

System 2 is overs

System 3 is unders

I'm hoping systems 1 and 2 are running cold and they'll catch up to system 3, but chances are system 3 will probably come back down to the levels of the other 2.

I could start a thread and post the system 3 plays

roll with it.....

Would be interested in seeing how this system fairs out also.  Is it a system or are you handicapping ? And just my 2cents but if it is working maybe instead of going too large if your not comfortable with that maybe just increase your wagers incrementally .                                                                                                    Best of luck as always and look forward to seeing your thread .
