go to skills snapshot after you have done initial training session right click on the red bar for the secondary you just trained, from drop down menu select inspect. you will see TD width ??% highlighted on the right
Then get that number and multiply by 150 and hit %. thats your learning speed
.i.e. your fighter is 1-- for subs, you train one session, 1-1 elite coach on submissions, after training do above, say it is TD width 4.5%.
