That simply isn't true and is the reason I urged to reread pp. 375-377. It makes no difference what your bankroll is. By using r-a indices, the lowering of the variance immediately permits you to increase the size of your optimal bet, thereby allowing ultimate e.v. not to suffer.
There is NO DOWNSIDE to using r-a indices, and people who advocate otherwise are laboring under a misunderstanding of the concept.
