Hmm...good news is that your cycle is far along if your levels were so high that the 50% pwc didn't bring them down much. If you've got the willpower and your backs not too sore from the first pwc, I'd do another to get them down further. There's really no harm in pwc's during a cycle as long as you remember to dechlorinate, they're just not normally necessary except midway and at the end. Go ahead and do another (75% wouldn't hurt) and try to get the nitrItes down a good ways so you can measure them clearly.
I think you're just about done with your cycle in the next days or week. If we don't get your levels down far enough you may not know when the cycle actually complete.
