60r20 OCD ... fail

I feel robbed and violated! Target was sub 1;50 splits and after hitting the first at 1:49.7 I turned it into what I thought was the perfect OCD row - but alas I was robber! nice and sweaty. Got ahead cold at the moment which is mainly sinus - so HR might be a little elevated from that and a few hours missing in the sleep last night. I have in my prime rowed at the pace/split/rate at 70% HRR - this ended at 85 to 90 % HRR
