Anyway... A doubling of processor speed should give a rating increment of approximately 70 points (give or take some, it's the right order of magnitude...) So, a factor f = 2 gives r = 70 points A factor f = 4 gives r = 140 f = 8 gives r = 280 etc In general: f = 2^(r/70) or inverted r = 70*ln f/ln 2 where ln is the natural logarithm (anyone got a formula editor?) f = 200/180 = 1.11 and this is the factor you are considering. Insert in the above formula to get r = 11 rating points. Barely measureable... I have not taken into account any assumption about diminishing return. Ralf
