I tried smaller correction steps on 1.1.53 and 1.1.69 - anyway Ego looks keep target faster in 1.1.27.
Seems 1.1.70 is answer!
[1.1.70] - testing
* with the given scheduler priority lambda_target lookup starved (got slow) under certain (very rare, therefore hard to notice) conditions. So any previous (after 1.1.27) is considered experimental and will NOT be released
o This should be fixed in 1.1.70 but we apply more testing specifically about this
