About 3 weeks ago I strained a tendon where the bicep comes into the elbow. It was fairly painful doing day to day stuff and I even avoided carrying general objects in that arm.

It's recovered well since then, I can swing a racquet, carry stuff, do pushups and such with no pain.
I tested it with three pullups this morning. At the top, as my chin got over the bar it feels like the tendon just moves or twitches a little bit. It's not painful, but it still makes me think I should avoid bicep heavy, pulling movements for a while longer.

So my question: is it worth doing partial pullups, with about a range of motion (avoiding the twitch point) while it fully recovers? Or just lay off completely?

I don't want to get weaker.
