5 rounds of 2 minute AMRAP of row 250 m and in time remaining max DUs. Rest 2 mins between rounds Workout

I did this workout early in the morning.
I like it and it's a good high octane conditioning WOD with Rowing and DUs.
Work 2 mins per round, rest 2 mins between rounds.
Row 250 meters, when completed, do AMRAP of DUs in time remaining
The row felt pretty good, but arms were getting a little blasted occasionally.
I had the damper on at about 6.5 and was getting my sets complete in about :48
I did: 78, 68, 75, 68, 68 (total=357) (I was having a lot of problems and trip ups with the DUs.) I think I have to change the rope or play with it. I was tired but the rope was tripping me up quite a bit more than normal.I messed up on my 4th round of rowing. I starte to row and realized it was just for time. I had to change the settings and got it going at about :15 seconds past.. so I basically went until 15 seconds had passed, and had that much less time to recover for my last round. Just the stress of getting it fixed was the issue really.
Good WOD. Those 2 mins. rest go by quickly.
