I invert and turn the tank gently (90 degrees, so that the inversion starts at
various places around the tank). I never found the twirling very effective on
its own, although I think I would give a couple gentle back-and-forth ’twirls’
on the 30 second marks if I was agitating only on the minute. But then I
misplaced the twirly thing, and never really missed it.
I *alway* put a spacer or empty reel in the tank to prevent the loaded reel
from moving up and down during agitation, and I use a standard amount of
developer that leaves only a small airspace at the top. I normally use
“replenished” X-TOL, so the number of loaded reels probably doesn’t matter.

Right from the start back in 1986, I found that that TMY was much more
sensitive to agitation than Tri-X. Indeed, I gave up using stainless steel
reels with open centers because even the difference in agitation between the
centre and the rest of the roll made a visible difference. (I went to
Kindermann plastic centered reels for 35mm, or Paterson reels.)
Fascinating - I can't say I've ever noticed this. Are you inverting or twirling
in the
plastic reels?
Thanks,
