I went through something similar years ago when I tried to get a sub-8 min 2k. Didn’t manage it, faded at the end. It’s awful when you see your split time going south and you can’t seem to do anything about it. I ended up with 8:05.
Found your stroke rate interesting. Similar to my stroke rate actually, but all the other girls I was rowing against, including the heavyweights, had higher stroke rates than me. They basically all seemed fitter/faster-moving, while I had good leg power.
I didn’t do much aerobic capacity work, like you are suggesting. That might have been the missing link.
