Sure it does, and in ways that are just the opposite of what you are suggesting (i.e., that efficiency is more fundamental that effectiveness).
Effectiveness (spi) is the maximizing of energy (wattage/time) expended
with each stroke.
Efficiency is using high ratings to get the
optimum time (wattage).
For lightweights, as tested, shown, proven by E-L-S, this is right around 8 meters per stroke.
Spi (effectiveness) is, by definition, higher and higher then 8 meters per stroke.
It is not possible to row at 8 meters per stroke, and at the same time row at 10, 12, 14, or 16 meters per stroke.
In training for rowing, effectiveness is more fundamental than efficiency.
Why?
But, if so, it is still not the same thing. They are opposites.
Whether effectiveness (spi) has some importance to practice, efficiency (8 mps) is the objective for all training.
You can be _very_ effective without being efficient.
But you can't be efficient without being effective.
Both are true, because you can't compete at 8 mps, while maximizing energy output (spi) for each stroke.
Effectiveness = watts/ time = spi
Efficiency = highest watts = 8 mps

If you have no stroking power, you don't go anywhere very fast when you raise the rate.
As in your case, which is entirely the norm for 60s lwts.
The issue with efficiency in rowing is not just how to row at a high rate.
This is not exactly true, because rowing at low ratings is highly subject to body mechanics like height, torso height, arm length, and relatively shorter legs.
Rowing with a high rate is a cinch.
Rich, are you sure about this?
Even this morning you said you don't have the aerobic capacity (efficiency) to row at high ratings.
Personally I feel that you can gain this with practice, and that it is not that far away from you.
