The Feb 2 boost was about 3.4 km in Mir's apogee (99033.62215070)

The Jan 29 boost was about 3.5 km in apogee (99029.93231147)

The Jan 27 boost was rather small - enough so I can't see it in the TLEs.

It seems strange that these boosts were scheduled as three separate burns,
I suspect that it may have been to tweak the orbit to match the sun angles
for Znamya over the planned target cities.
