Started at 20,500 Defence. only trained 10E every 100 INT.

I know rng affects gains but I think this is still helpful:

• 100 INT
  You gained 58 defence, using 10 energy! 
• 200 INT
  You gained 100 defence, using 10 energy! 
• 300 INT
  You gained 145 defence, using 10 energy!
• 400 INT
  You gained 166 defence, using 10 energy!
• 500 INT
  You gained 204 defence, using 10 energy!
• 600 INT
  You gained 219 defence, using 10 energy!
• 700 INT
  You gained 227 defence, using 10 energy!
• 800 INT
  You gained 246 defence, using 10 energy!
• 900 INT
  You gained 283 defence, using 10 energy!
• 1000 INT
  You gained 286 defence, using 10 energy!
• 1100 INT
  You gained 285 defence, using 10 energy!

up to 500 int the increase in gains is a lot more noticable

Was trying to track this but I messed it up. Nice work

This is amazing! Really all it needs is more data and then you could get a mean and median average, because that 500 INT "jump" could just be some RNG with the 400 and 600 INT.

The only true way to track this is to start int training after gym growth cap.  You are forgetting you are getting increased gains from the hidden gym growth cap.  And to train past your gym growth before int cap is definitely not the meta or recommended. 

There is no real way to know unless your gains are completely topped out remember you get increased exponential gains all the way up to around 40-50m in a stat 

Edit: all that being said upvoted for the cause I tried to do something like this when I was in that phase but the numbers got screwed thanks to gym growth stat
