Suppose I set the kelly-factor to 0.5, and then adjust minimum chip size to $25. The ROR now jumps up to 20.3%, even though the k-f is set at 0.5. Does this mean that the k-f is affectively 1.25? Would this still be considered as "optimal" betting?

Also, why does CE become -$24? I thought CE is 50% of EV.

See link below.
