I have been looking at how to factor age and weight when comparing rowing times. The following link is for 2000m, but I mainly row 5000m, so I will linearly extrapolate (not 100% accurate but acceptable).

Two example rowers are shown below
Age
Weight
Time
Person 1
31
100
17:58
Person 2
33
70
22:08
17m 58s = 1078 seconds Weight adjustment: 1.059/0.979 = 1.082*1078 = 1167 seconds = 19m 27 seconds Age adjustment: 1.6seconds *(5000/2000) = 4 seconds. So person 2 would have to complete 5000m in approximately 19m 31 seconds to be on par with Person 1
17m 58s = 1078 seconds
Weight adjustment: 1.059/0.979 = 1.082*1078 = 1167 seconds = 19m 27 seconds
Age adjustment: 1.6seconds *(5000/2000) = 4 seconds.
So person 2 would have to complete 5000m in approximately 19m 31 seconds to be on par with Person 1
22m 08s - 17m 58s = 250 seconds ~ 100 seconds over 2000m Person 1 would have to be around 73 years of age before Person 2 can land his spacecraft and win!!
22m 08s - 17m 58s = 250 seconds
~ 100 seconds over 2000m
