Different extruder steps between MK3.5 and MK3

I did the conversion from MK3s+ to MK3.5.
However, I have fitted a slightly modified extruder. A modified version of the Bunny Science.
After the conversion, I had to correct the steps for the gear ratio, which was 280 to 980 at the time.
After the conversion, however, I noticed that the MK3.5 has 266 steps. Can anyone give me a hint as to why?

It should be the same old MK3 extruder. I thought they would at least be the same.
I have now changed it to 980 anyway. However, I always over-extrude a little.
If I convert it using the new extruder values, I should now go to 931 steps.

I think I'll test it first, can anyone confirm the 266 when reading it out?
