Leg imbalance getting worse

First off, I have a Rotor Power, hence I am being told by what they say before anyone asks.

Over the past few months, I have noticed that my leg imbalance between L/R is starting to increase. Over the winter it wasn't too bad showing generally 49/51. However, this has started to grow and over the past week it has now got to 46/54.

I am trying to work out why it is happening and what I could do about it. Some of the thoughts are
- I am quite tired at the moment and I am naturally favouring my stronger leg
- I have been carrying an ankle injury through running and the pyhsio is now sorting it out and so I am utilising my right leg more without realising it

Here's an example of my ride home from marshalling last night: https://connect.garmin.com/modern/activity/799267385

Any thoughts appreciated. Thanks in advance

    How confident are you in what your PM is telling you?

    if you've got an injury then it seems most likely cause, you'll instinctively go easier on it

    either accept it until you're over it or use the pm data during ride to 'force' yourself to balance

    afaik most people have some l-r imbalance even when perfectly fit and healthy, if you weren't being told by the pm data would you ever have noticed?

    also, as imposter suggests, when was the pm last calibrated?

    +1

    I wouldn't totally trust the figures. - my balance used to be 49/51 for many rides when seated. But then my PM (Power2Max) failed and a replacement was sent to me which now shows my leg balance is apparently a fairly constant 43/57. Definitely not my legs that have changed suddenly!

    Fatigue has a massive influence on L/R balance averaged over a ride with lots of stop/start pedalling, etc. IME.

    Have you done some continuous efforts with no coast and looked at those numbers?

    Even then though I wouldn't worry too much about it.
    More problems but still living....

    Thanks for the replies.

    Yes I am massively fatigued at the moment and probably need a rest. Also, a good call on re-calibrating, as I've swapped it between bike a couple of times recently and haven't done the recalibration.

    Last continuous effort was last Tuesday's TT and it was reading 47/53
