ken: kelly fractional betting

[ken]

I'm still struggling with Kelly fractional betting.

For a given game at full Kelly the SCORE is 50.

If I'm betting 75% Kelly, my ROR is 6.9% and my growth rate is
94%,based on DS formulas from the Parker pages.

Is my SCORE now:
50*75%*94%=35.25 ,or
50*94%=47 ,or
Am I completely off base?

Thank you

You're completely off base. SCORE requires that you bet Kelly, otherwise it isn't a SCORE anymore. Hourly win rate is a different matter. If you bet 75% of Kelly, and you don't resize your wagers at any time, you will win 75% of what your full-Kelly win rate was.

Your ROR doesn't matter, because you aren't using it to size your bets; you're betting 75%, period.
