Updated!
For your regression, Trivia #3 would not need to be regressed either since the claim was posted after the regression post, so your pre-regression TPE total would actually be 668 which means you would only need to regress 668 * .2 = 133 TPE. So you removed 3 TPE more than you needed to. You already added 2 back, so you get 1 additional point added back. I went ahead and added this point back to Endurance since that was an attribute you regressed and was where you added your other TPE this update. So you now have 84[2/10] Endurance and 573 total TPE.
