Are Hit Text wrong?

I need some help to understand my damage output. I'm your typical health build in mid game, farming Tier 9-11 and placing high in Plat. I turned Hit Text on midfarming run Tier 9 for Elites. They have around 100q health. My bullet damage is climbimg from the high T's to the low q's and further up to 20q or so for minutes of game time. I must have landed hundreds of hits over 10q. Finally the Elite crashes to thorns. Now my question: why doesn't it die earlier from bullet damage? Am I getting somethign wrong? Do you need more info to answer that?
