Limit Bouldering attempts?

[mcd]

How many real attempts are you able to make on your limit problems before losing power? Has this increased with training? I find I am able to make only between 12 and 15 really solid efforts on my limit problems so maybe 50 - 60 moves in a session before I start to loose the ability to try hard. I am also still trying to find problems that are actually limit, instead of very hard, so I guessing true limit problems will decrease this volume of work even more. How does this line up with your experiences?

15 attempts seems a lot to me if you are limit bouldering.

I probably would only do about 8-12 attempts. 4 to 6 on each of two different probs.

I find that my limit probs can be tweaky and trying to many times at the same move in a single session risks injury.
