I ride biopace.
It helps on hills and I can spin a little faster.
Strangely, a biopace feels "rounder" than a round ring.
Shimano might have meant a 44t biopace ring as a middle or inner ring on a multi-chainring geared bike.
If so, Daveed might consider flipping the ring over so the chainring bolt countersinks go up against the crank star.
Biopace rings have a "direction," and, if an inner ring (sounds like it), this will correctly orient the ring.
I ride with my 42t biopace ring oriented this way, and it works great.
By the way, having the countersinks against the star gives more room around the chainring bolts for centering the chainring.
Taking extra time to center the chainring lets me tighten the chain more, so that it gets almost tight at the tight places and not too slack at the slack places.
The tightest place should occur with the top pedal at about the 12:30 or 1:00 position, a little ahead of the seat tube.
