Sure, I've modified your source code to use float for komi and get 75 
(!) kpps on the same box above.

It's ok for almost all games but you can also use a classical technique 
of doubling komi that concludes having all internal scores be doubled.

I've tried this and get 104 kpps but I'm not sure it's correct (very 
slower than expected).
