Updated!
Activity Check #175 and Weekly Training for 09/20-09/26 are not included in your pre-regression total, so your regression would actually be calculated from your previous TPE of 1381 so it would be 1381 * . 2 = 276.2, which rounds down to 276. So you regressed 2 TPE more than you needed to. However, you also added 1 extra TPE because you claimed 3 TPE from Activity Check #175 when it's really only worth 2 TPE. We can cancel that out with the TPE you would get back from regression, so you would end up getting back 1 TPE from regression which I added to your bank. So overall, your new totals after this update would be 1112 TPE with 1 TPE banked.
