The progression of specific torque capacity is something that develops extremely slowly for someone who is already accustomed to this type of training. A 10% increase per week is unrealistic. Even in terms of power, 10% is a lot. I can’t see someone doing 60 Nm one week, then 66 the next, then 72 or 73 Nm, and so on.
This idea of 10% per week could refer to “general” training load (TSS, for example). Even then, 10% per week indefinitely is excessive. So this “rule” feels very vague to me and extremely limited in practical application.
As @Gerald said, progressing the total time exposed to the stimulus per session, on the other hand, might be more feasible (but I’m not saying that’s the way you should be doing it). Ex.: you do 8x 2’ at 60 Nm with good execution. The following week, increasing to 9x 2’ means ~10% increase in total time, but keeping the same target intensity. That’s feasible and I can see some logic on it. After some time, you may even return to less time, but in a increased exercice load (target Nm).
Your question needs more detail before it can be properly answered. What kind of torque exercise are you doing? For how long, and how? What does the structure of your torque sessions look like? How has the execution been lately?
