Narrative:
While turning over ihd, the controller questioned our lead distance in the turn [for outbound radial interception]. We advised him it was computed by the FMS. Upon landing in pit, we discussed the occurrence with the sector supervisor (ZOB) and he advised us he would address the software issue with our supervisory personnel.
