I think it's an entire article about thermal throttling that never once mentions it.
that would be even more dissapointing of course, but all that's given in the article is the wattage chart
actually, in the article linked at the top they say this: "The situation is much worse on the smaller MacBook Pro 14 with the M5 Max, where the maximum power input is capped at 97 Watts (even when you use Apple's 140W PSU or an even more powerful 180W USB-C PSU), which results in a battery loss of 15 % during our one-hour stress test."
so it really does sound like a power throttling thisng to me https://www.notebookcheck.net/Apple-tries-to-hide-that-the-p...
Either way, this article is almost entirely about a symptom without root cause analysis.
