My experience says no they will not tolerate 50+
Must qualify that statement.
I can have a couple pushin 50.1 or so.
If I see 51.x it might not have puked yet but it is likely.
Some quit before 50A.
Seems like 49A all day works.
Way past recommended with temp(for most) and current.

I lowered all volt 1 selection and it helped everything.
-0.0439
HW error dropped from >0.8% to <0.7%

My results could be unique.
If you try it please report results.
Different PSU/wires combo might produce different results.

YMMV
