I've long understood that an ideal recovery has a slight acceleration

Okay. "slight acceleration" of what?
The slide?
Does this acceleration continue right into the catch?

yes and yes.

I'm truly curious, because I've never understood that as an "ideal
recovery", and would like to see the reasoning behind it.

The hull speed is slowing during the recovery, by slowing
the early part of the recovery and accelerating toward the
catch, you are keeping the hull speed more even.

Just like a rush out of bow and a slowing down toward
the catch will create a peak speed right after the catch
and a slower speed toward the catch, the accelerated
slide evens it out.

I call it an 'ideal recovery' but I've never coached it, even to
nat'l level scullers. It's hard enough getting catches timed
right, that getting better catches is more important than
that recovery nuance. I've talked about it, of course,
but never tried to pattern it in.

My nod to it is to get people to clear their hands from their
body before they start their swing, and swing their
body past the vertical before starting the slide, trying
to keep the handle speed constant.

Later~ gone a few days for a soggy bike and surf trip.

Mike:
Thank you for providing these details, I disagree on virtually every
point of it, but not to worry, I'm not going to waste anyone's time by
describing why.

I hope it clears up for your cyling trip.

For Kieran:
I did the "no oar, sliding" exercise today (again) and advanced the
system rearward (sternward) for a while, then forward for a while,
exactly as I had described (opposite the direction of the rapid hull
travel). I used a reference point of the rigger stay that was 90deg to
the hull when I was at full leg extension, moving it about 2 feet to
the stern (rushing the body sternward) and then 3 feet back to the bow
(rushing the body bow-ward, netting forward hull travel). Damn, the
terms are confusing to deal with, but no typos as far as I can tell,
after reading this several times. I did have a 3rd party, that was a
witness during the exercise read this, and they confirmed it accurately
decribes the results they saw.

Unfortunately, that only confirms and reinforces my view that I am
indeed correct in what I said originally. So please feel free to
continue to explain why I'm wrong, the reasoning will still be
interesting.

No, I was not careful on the "slow slide", I just did it much slower
than the rapid slide and equal distance.

Yes, I had a nice floating reference point on calm water.

Yes, I was not even holding my oars, they were floating parallel with
the hull.

Apologies for lacking political graces when presenting facts, I simply
do not understand why they are necessary with such a self-declared
open-minded and intelligent group. Hopefully that is enough of an ego
stroke for today.

Cheers.
