HR drift and variability in Z2 on treadmill

Good morning and thank you in advance!
I am 53, and have ADS. I am a ‘born sprinter’, loved the 100m and 200m as high schooler, and last year bonked on Rainier at 12,500 and had to turn around. I had been doing hard 1 hour elliptical work outs and hiking and just didn’t realize this wasn’t going to work.I got home, started running last summer and fall, then decided to train for Rainier again and signed up. I have been doing 1 to 2 hour treadmill sessions over the winter with a 15% grade and speed starting at 2mph that gets my HR up to 120 (my AeT). My speed has increased over time from 2mph to 2.4 to get into a good range.
I have been backing off on the treadmill speed by about 10% to keep my HR under that mark and more when my HR spiked. I have 2 questions:
1)There is a lot of ebb and flow in my HR. It goes up to 124 and then down to 116. I used to micro-manage this with frequent adjustments in speed. Is this ok or should I just pick a slower speed to start?
2) in a two hour workout should I allow my HR to drift up to 130 in the second hour if I can continue?Yesterday’s work out is attached. I started at 2.4 which I cut to 2.3 at the 30 min mark as my hr started to increase significantly. I kept the treadmill at 2.3mph and 15% incline and finished with last 40 min average HR of 123, max of 131, and min of 112.
Be a micro-manager, start easier, or just let it go and take the averages?
Thank you!
