Damage doesn't add up like that though. The excess damage will still be shown. E.g if a character has 1000 HP and takes 900 damage he has 100 HP. If he takes more 200 damage after that, then the game will say that the damage done was 200 even though 100  of the damage wouldn't actually have any effect.

The only way to get an exact number (without spending hours of punching enemies for 1 or 2 damage) is to poison the enemy, NPC, boss etc. and let the poison do all the work. Excess damage will for some reason not show when the target dies from that damage tick. And the only way to get Tarkus poisoned would be to get invaded and have someone poison him. Poison Mist and Toxic Mist are the best ways to test since they don't deal any direct damage and is free to use.
