I edited my above post meant to say lvl 42. I used your guide to calculate the difference between each stat changed, then added that difference back onto the original number to predict the next stat change.

Example regular original gems had a stat change at lvl 9 and lvl 25. So I did 25-8=17. Then I added that back into most recent stat change 25+17=42.

The tarlok gems are a bit harder as you have to do the math for the primary and secondary stats separately almost like they were two different gems.
