So the group ride I did last night, turned out not to be a group ride, so no rubber band effect

This meant I only got on there 30 seconds prior, so had zero warm up, and then felt I had to go harder than intended.
I was planning an easy 100w 20 minute spin, but it turned into a 191w ~17 minute effort, so I tacked on a 7 minute cool down as well.
I fully expected todays ride to be tough, and presumed this would make it tougher - the first 2 pairs were perfectly ok, and then it got progressively harder, and my cadence dropped, though I don't think it was horrifically low.
Cadence:
88/88
84/82
86/80
78/80
75/72
I'm also operating without my BIG fan at the moment, and it was some 18c in the garage at lunchtime, so wondering if they might be contributory factors.
I see conflicting advice/reasoning about whether to abort/lower the percentage when your cadence drops.
I'm not naturally a higher cadence rider, my fastest rides tend to be more around the 78 cadence, I have a naturally high hr, so my theory is that that lends itself to my body getting on better with a lower cadence way to get the watts out, rather than loading the cardio.
As long as I am hitting those targets (ERG leaves me little choice) I would have thought it is still of a benefit - even getting out of the saddle.
On a real climb my cadence might even drop to 60 or less, and I'm bound to be out of the saddle on a climb, either to get some more power out, or just for a change of position, stretch etc etc.
I rated this as Hard, and it looks like it has adjusted my workouts a bit as a result.
Interestingly, I have this plan running up until I go to Spain for 7 days with my daughter.
On the TR calendar I've basically put nothing down on there and for the Easter weekend, as I don't know what I will be able to ride, I'll probably leave her sleeping in, and try and get out early for a couple of hours, maybe 3-4 times would be nice, anymore is not feasible.
Due to the calendar being empty, TR is interestingly calculating my next AI FTP as coming down 1.8% to 219, which would be undesirable, so I'm hoping that is purely down to the fact I have 10 days in there with no planned activities.
I won't be riding with any form of power for those 7 days, though will have HR, so presumably the intensity will be calculated by TR based on the RPE I give the rides, and maybe it's AI FTP estimate will not decrease?
I'm not worried about it, it's just an arbitrary figure, I was just curious, as last time I used TR, it didn't have this FTP forecast thingy.
I also thought it only calculated your FTP every 28 days as a minimum, this month it gave me a new FTP of 221 on March 6th, which I was expecting, but then it popped up of it's own accord on only March 9th, with another new one of 223, which I thought was a tad odd no?
In the interim I had completed two TR sessions, and two Rouvy events, though only one was a properly hard effort, but that was the short ~18 minute one yesterday, I also can't recall if the ne FTP was before I completed that race or not, it could well have been actually.
