"Optimal" f is only "optimal" because Vince defined "optimal" to be 
the approach that produces the highest TWR.  It's definitely not the 
"optimal" place to trade if you value your account.

*If* you decide you like the optf approach, you may very well find 
that the "optimal" place for YOU to trade is a much much safer and 
more conservative value of f than Vince's "optimal" value.  It's not 
an exact science any more, but the exact science approach doesn't 
work very well in real life, and it might work well for you.

Or you may decide optf is totally the wrong approach, in which case 
another formula might be the right answer.
