What are doubles, pseudo heals, etc? I'd like to prevent those (or know what to do if they happen) if I can..
So for the 35 heals, just make her heal 34 times then stop damage altogether until under 10 minutes?

I'll use rough number estimates to try and explain, but it's tough to explain which is why I just said focus on getting as many heals as possible.
Emp heals at ~10% hp, which brings her to ~50%. If aggro messes up, or the damage done when she's close to healing is either too little or too much she will double heal, going to ~90%. This usually counts as one heal, sometimes it doesn't count at all.
When you have 35+ heals, and the timer is <9:59, if you don't do enough damage fast enough when she is in the "healing zone" (~10%-0% hp), she will "pseudo heal." This is the same amount as a normal heal and it amounts to nothing besides frustration and annoyance.
