Shifting advice Bosch performance speed 4Gen

I have a Gazelle Medeo T10+ and am loving it, but want to make sure I understand the torque, cadence, and speed sensors on this Bosch gen 4 motor. I have found my shifting to be smooth and usually just back off on my peddle-pressure before I shift, so I help the chain and gears. I think I have heard this as recommended, specially if using a lot of torque on a hill or at high speed. Is my understanding correct, or is there some sort of built in shift sensing and I do not need to ease off on my own pressure? I do occasionally ease off too much and find I almost stop the chain motion and then the shift occurs when my pressure reapplies. Have not had any hard shifts, but want to make sure. Thanks.

I have the same motor in my Cannondale and I ride the same way. When I want to shift gears I decrease the pressure on the pedals while shifting.
I seldom ever shift gears while going up a hill. I prefer to have all my shifting done before I start my climb.

The shift sensor in the Bosch system eases off on the motor during a shift to smooth out the shifting process. It is still very beneficial in reducing strain on the chain and derailleur cogs for you to do the same regarding the power you are applying during a shift.

I have an Allant+7 with a Gen 4 CX updated with EMTB mode. I shift going up hills often but I also let up slightly at every shift.

The regular shift sensing in Bosch is not reliable, it is a crude software implementation don't count on it.

Just keep on easing off right before shifting. It is the best practice.
