Dear Lord TECHWAY,
I understand your question and would say the short answer is;
In theory, you don`t need to yellow bar and should get big payouts as a matter of course.
In practice, it may well be different.
Perhaps like myself, you have heard of people taking a much less scientific approach, in hitting each BG with all they have got.! Some of these people have said that they receive big payouts just fine.
This would suggest that yellow barring is indeed merely a way to know when a big payout is due & not a necessary process to get maximum payouts at all.!
I am not advocating this idea but trying to answer the question posed by you. :)
Obviously, more data is required to give a precise answer but I hope it at least addresses your question.
If anyone can add further info on this it would be helpful no doubt.
Wyz.
