How would one compute the estimated error of the system time from UTC
at any point in time from information given by 'chronyc tracking' ?
Is 'System Time' + 'Root Delay' / 2  + 'Root Dispersion' the correct formula ?
If yes then then all these 3 values would be helpful to be put in
tracking.log (or maybe other log) regardless
they are before or after an update as long as they are consistent
(they refer to the state of time from the same moment).

For consistency maybe they should be the values 'chronyc tracking'
would display after the last update.
