you get as many tries as you want, as long as the "tries" are contiguous. Let me give you the real timeline:
1) weighed in with clothes. Didn't make weight.
2) took off clothes. Didn't make weight
3) took off ring. didn't make weight
4) spent a little time cutting. made weight.
So in other words, the first three were one right after the other with clothes/accessories removed, which is not at all uncommon.
His helmet was stifling, it narrowed his vision. And he must see far. His shield was heavy. It threw him off balance. And his target is far away.
