Only Worth So Much
I believe the indices can change depending on your bet, but there is not a lot to be gained in this thinking. Proper use of RA indices are worth about 1% to 2% in raising SCORE.
A new player should probably learn RA indices if available. If not available the EV indices are fine.
If you are a veteran it's a matter of choice if you want to put in the effort to learn RA indices in order to raise your SCORE 1% to 2%.
However:joker::whip:
Let's say an EV indice for a double play is 3 but the RA indice is 5. It does not matter much which you choose as long as your bet is within the same range. This is probably why light indices are effective, many indices have a range going from ev to ra anyway.
Hmmmm
What if you have a TC7 bet out? but the count is now 3,4 or 5?
Probably the answer is you do not double.:joker::whip:
So you may just want to make sure your bet TC corresponds with the indice TC you are contemplating using, this will often be the case anyway because of the TC theorem.:joker::whip: Also, this is not much of an issue if you have a low ror. If you bet full kelly with frequent resizing then this is more important because you can be overbetting your double in this scenario :joker::whip:
