Hi sorry for the English.

I use a smash studios have its first version, which has some shortcomings but it works very quickly. The new version of the calculations are carried out more: / My point is exactly that, the conversion time, if it is composed of, say 50 equations on the complete version that will convert it to an earlier 2-3 seconds, the new program will do it in 15-20. When you enter the data after entering each variable x1, x2, x3, etc., is a cumbersome because let's say 30 is the conversion constant throughout the conversion time in 1 minute. When a new version of 30x15 = 7.5 minutes. It `s too long: / Any cure for that?
