Very high HRVAlpha RR/A1

I just wondered if anyone who knows about HRV could offer an explanation of what is going on here.
I did a 5.5 hour ride yesterday (>2000kJ), felt great on it and didn’t feel too fatigued either last night or this morning. Had a small breakfast then jumped on the turbo to have a VERY light 30minutes just to spin the legs as they were aching a bit.
This is the RR/A1 trace I got. Unbelievably high. I would normally expect the value to be consistently around 0.35-0.4. max wattage was only 60W! Like I said very easy.
No artefacts except .33% for a bit in the middle.

It seems that RR, A1 or both are not correct. I’m quite sure there is some issue on measured or processed values.
How do respiration rate and A1 look for this activity?

A1 just kept dropping to very a very low level.
Respiration rate seemed to be OK but then increased seemingly for no reason at about 15minutes. Power reasonably constant and HR up to 85/90 which tends to be my minimum HR when doing any exercise (Resting normally 56, this morning 60)
