Maybe Bitter Root only boosts base health, rather than health granted by other bitter roots & infusion. (I suspect it also doesn't count Guardian Hearts, but that's not as much of a surprise) In addition, the boost might be persistent, rather than a one-time addition.

Taking your Game 3 as an example, The first root gave the 'correct' amount. Now at the second root, you had 682 health. If Bitter Root's boost is persistent, then rather than subtracting the initial 43hp gain, we need to divide out the fraction of increased health. Taking (682 / 1.08) gives us that amount: 631. (631.481~, more exactly). Multiply that by 8% (631 * 0.08) and you get 50.48, and 50 was your observed health gain.

Looking at Game 2, I'm guessing you had an infusion between those roots, but note that each root gave about 78hp. (The 79 may have been a difference from rounding? The true value could be something like 78.3) That indicates that root works off of some hidden number that doesn't change based on how many roots you have: I'm guessing based on your "base health" before other roots and bonuses from infusion.

So, tl;dr- The health bonus from Bitter Root appears to be based on your base health before other bitter roots or infusions. As well, the health given per root adjusts on levelling up so that each root is worth a consistent 8% of your base health at all points of the game.
