xoto10andJoost VandeVondele dd1adce748 Increase base time use and limit max used. 
This change increases the base part of optimumTime at all depths. It also reduces the size of max_scale and thus maximumTime by using a linear scale instead of pow(x, 0.3) and by limiting max_scale to no more than 7 (previously as high as 8 or 9 at very high depths).

Tested using the closedpos book:
