Position calculator in middle of screen

This JavaScript race time predictor calculator allows you to predict your race time for a second distance by entering a time for a given distance and the second distance for which you wish a predicted time.

This formula was derived by Scott Diamond and is used in his shareware program Runstat

The JavaScript is based on the formula T2 = T1 x (D2/D1) * (1+y)^{[log(d2/d1)/log(2)]}   where D1 is the race distance for which you have the time T1 and D2 is the second race distance. T2 is the time that the JavaScript will compute, and Y is the % slowdown for the longer distance. The standard/default value for Y is 5%. From my personal performances, 4% produces more accurate results.
