Average intensity factor

So I am wondering if anyone looks at their average IF for blocks of training ? It’s not something I see talked about much but I think it’s probably an important metric to consider. Currently in my last 10 week block I’ve done 58 hours and about 4100 TSS. This averages to 70 TSS per hour, or an IF of 0.84. I have the suspicion that as training hours goes up average IF must go down to avoid burning out, but just how much I’m not sure. I’m not even sure it depends on what your doing. This last 10 week block I did mostly vo2 max and endurance rides so more polarized but I’d guess that sweet spot work would also look similar.

Easier just to look at ramp rate, also avg IF doesn’t encompass what is going on, just look at TIZ distribution
