Max is discussed to a small extent in the TSL interview with TZ about his book.
The interview was recorded on Oct 18 and published on Nov 30.
I'm mostly *paraphrasing* below. The only verbatim quotes are indicated with quotation marks.
About a five-minute chunk re Max's training plans starts at approx. 19:47.
Discussion of his work on quad jumps (esp. toe, and also axel, lutz, loop). He is capable of a lot more [in terms of jumping] than he has shown, says TZ, who adds that Max's emphasis going into the GPs is spin levels and GOE -- also performance, which is "top priority." DL asks why Max prefers the quad sal. Quad-triple combination still a huge part of commitment day for Max.
At approx. 40:25, TZ's speaks again of Max's goals -- for spins and for being emotionally connected to his SP and FS music ... able to express the music with his body and also his face. "That's a huge thing we're working on." Quad-triple too.
Other Max-related bits:
Dave asks about TZ making Monday a "hard" day of training and whether it starts with the first session of the day. TZ mentions that Max loves to hit hard on the first session ["surprise, surprise

"]. (The discussion leading up to this mention starts at approx. 10:45.)
Within a discussion of the importance of hydration (starting at approx. 11:43), TZ mentions Max's fly-by water-bottle grab on practice sessions at comps. He doesn't like to stop and stand around. And after a swig, even as Max is moving, he'll place the bottle back on the barrier or hand it off to TZ.
Max is "in such impeccable shape (for other reasons)" that he doesn't really have to do double run-thrus. Has done them within the last four years, but not maybe within the last two years. (This part of the discussion of double run-thrus begins at approx. 18:44.)
Great photo of Max at the Festival of Lights Parade in Colorado Springs.

Going out on a limb now, but .... I think(???) several signs are pointing in the direction of Max having a small role in "Ice," an independent feature film centered around figure skating, some of which is being shot at the South Suburban Ice Arena in Colorado. If(???) my hunch is correct, hoping for a fun experience for him and maybe something that we eventually will be able to see.
