Edit: It didn't went over 71,7% (again). I did some Arp tests then. I can't get the optimizer to use any Str gems in combination with Arp gems. It's either all Arp or all Str.
I'm quite confused, as every test I run with Bold / Fractured both selected shows some of both if it is hovering around the cap. Mind pasting your settings in here so I can try to replicate? I've tried over and over to get it to gem over the cap and I just can't get it to do it.
Just to double check everything I started over from scratch, entered my stats into Kahorie's DK Sim, got new EP numbers, punched them into the optimizer. Still getting 1295 ArP. Calculation took exactly 1min30sec to complete. Here's the contents of my DKO file.
I tracked down your issue. Several posts (a page or so?) ago I mentioned that in making Jewelcrafting choose ArP gems if ArP > Str, that it would potentially go over the cap since the Jewelcrafting is dumb. When I turned off Jewelcrafting you are just under the cap. I'd recommend just subbing out a few ArP gems manually, as adding the Jewelcrafting things to the mix at this point is a bad idea for complexity.
Regardless, though it's sort of a deceptive behavior, it is also working as intended .
