Hello. I think it is time to revamp the skill calculator @
http://www.entropiatools.com
There is much improvement that can be made as far as accuracy goes. The first thing I need is data though

I am going to keep a running list of data points here and then use polynomial regression to get some equations.
Basically, I just need the tt value of the extracted skill chip and skill level that produced it.
I'll update this list as I get more points, please post here or pm me if you'd like to contribute. Hopefully we'll soon have enough for a better calculation.
Thanks
