I know the numbers matter.
Can't help you with that.
Don't ride the data.
My only suggestion, and it may work for me and not you:
1. Leave the HR monitor at home.
2. Leave the cadence sensor at home.
3. Leave the speedo or cyclo at home.
For six weeks, ride a lot, vary the terrain if you can, and work on being smooth.
Generally, when you drop from 52 to 42, you can drop a cog in the back and it's less jarring. Sometimes two cogs in the back.
Simply work on what tells your legs "thumbs up" or "thumbs down."
Once you get accustomed to riding more by instinct/feel, re-introduce the data.
Start with the cadence, then the HR. You may need to adjust your zones.
Forget the speed. Doesn't really matter, unless you are asked to maintain a speed.
Introduce that once you have a grip on your consistency and limits.
