Steps:
1. Record damage averages for Upheaval in Deliverance, Deliverance+Thrill of Battle, Defiance, Defiance+Thrill of Battle, Defiance+Unchained, Defiance+Unchained+Thrill of Battle. Sky, Stone, Sea - The Royal Menagerie was used as the target for easy cooldown resets. Critical and Direct hits were ignored.
2. Divide the resulted damage with modifiers found in the tooltips to get base damage without modifiers.
3. Compare base damage differences between expected and real values to derive true base potency.

It seems that Upheaval has a base potency of ~450 in Defiance instead of the 300 potency reported in the tooltip for both stances. There also seems to be a weird interaction between Defiance and Thrill of Battle damage bonus, where the bonus damage multiplier is 1.25+0.20=1.45 instead of 1.25x1.20=1.50 we see being used for the actual HP bonus. This could be due to some inaccuracy in the data collected to save time but if it is an oversight, it should be fixed.

Assuming this is all intentional, the tooltip should still be clarified for the massive base potency difference between the stances as the damage difference is not explained by the HP modifier alone.

Here's a small spreadsheet to document the gathered damage events:
