In my post I was a little bit short with my test desription, may be to short. For the accuracy evaluation my test grid consists of 1 million points of (R,K) couples with different values ...

Paul,
for my timing analysis I repeated the tests several times. For each run I (1) sum up the CPU times of all FUNCTIONs and (2) calculate for each FUNCTION the percentage of the CPU time. To get re ...
