There are a few films - Kodak T-Max films being three examples - where the "2x clearing time" rule of thumb would be better if it was a "3x clearing time" rule of thumb. They simply need more fixing.
As far as I am aware, you need to fix for significantly longer than 3x the clearing time before any bleaching effect starts to matter.
The only problem with using 3x the clearing time for all your film, is that it tends to delay your results longer than is necessary for lots of different types of films.

Yeah ... I was gonna mention that, but processing so-called normal film is complicated enough, and it didn't seem that the OP was using TMX/TMY &c so I thought I'd mention the extra fix needed times when he posted the typical "my TMX/TMY film is is magneta" thread when/if he crossed that bridge into the "exceptions to the rules" territory I agree with delaying one's results ! I barely have the patience to wait 1/2way though the typical 2x clearing time, 3x the clearing time would be like pure-torture...

I was not aware of that site. Thanks!

I dilute at 1+9. So given the recommendations at 20 degrees, I should develop for even less than my 9 min. That does not feel right.

This is a classic of stupidity. Whatever the Massive Dev Chart says, Ilford says for this dillution and temp to develop for 4:15 minutes, not 9 minites, which is why the photos are grossly over developed. Why do people who need this type of information go to an on-line source full of BS and unverified data collected from who knows who, when they can as easily go the manufacturer and pull the needed data off their website? Oh, I know. Ilford is the establishment, and they want to mislead you so you'll get bad results AND HATE THEIR PRODUCTS!

The Massive Development chart does not give those values...it has pretty much the same info as Ilford. The OP came up with 9 minutes from somewhere else!
