Providing that you do everything wright, you will understand from your data how edge is created on particular wheel you will follow ( play).
Every wheel is different. Some wheels will offer stable vb edge, some will only offer bias edge, some wheels will require you to do both , visual prediction and bias assessment. Every case is different, that's why understanding how edge is created is important. There gonna be cases when bias edge is stronger then possible vb edge, and others , where vb edge is stronger. It will depend on many factors. To simplify data analysis there are shortcuts.
If ball jump differences ( from spin to spin) i's huge ( 27 pokets of dispercion or more,) then you may ignore vb edge and focus on bias only. If ball stops where it falls, vb would do better.
Rule number 1.
Collect data till you understand how and why edge is created.
Rule number 2.
Continue taking data till you confirm edge.
While playing with the edge, it's important to recognise situations when it's favorable. It's much more profitable to wait till perfect conditions then try to explore situations for wich you have no data.
Other point is how to explore edge you have. Flat betting sucks. If you flat bet, mistakes gonna be costly. Use up as you go progressions. Set your betting the way that permits to win a lot or loose a little. This way when right, you win a lot ( comparing to initial bank ), when wrong, you just have session bank to loose.
Up as you go progressions permit to multiply your initial bank many times during relatively short playing sessions ( 100- 150 spins). Forget about up as you loose progressions or flat bet- it's a road to nowhere.
Be relatively conservative. Up as you go progressions are very agressive, add aditional multipier ( confidence factor) in your bet calculations. I normally set this multiplier to 50 %... only rarely l permit myself to use 100% , if l really sure about my edge and value it may take.
Remember, underbet will make you less money, overbet- kill bankroll. It's better to be under payed then not payed at all.
