The overhead is not exactly negligible, but is comparable to running a Scrum team. Recording is negligible, teams usually have a single meeting per week of less than an hour, though some have a daily Scrum type short meeting. The meetings are led by the team leader.
The TSP coach is most active during the project launch and post mortem. A launch seems to take about 2 days for a non-trivial project, with another day or two every 2-3 months. It varies somewhat, but these are typical. Figure 1 day of Coach effort at the end of development cycles (typically 2-3 months) for data analysis, 2 days at end of a longer project.
Training is a larger investment, with a most basic developer training taking 5 days, the more advanced requiring 10 days of effort.

Thanks for the above. Could I ask that you rephrase this as something I can add to the paper. e.g. references, learned authoritative statements, the usual drill. just add it as issue text and i'll add it in from there.

An informed estimate is that tracking time, defects, and tasks requires less then 3% of a developer's time. Weekly team meetings should require at most an hour, which 2.5% of a 40 hour work week. Team launches and replans average about 1 day per month or 5% planning overhead. (Crosstalk,"TSP: Process Costs and Benefits", James McHale, September, 2002, A trained coach can support 4 or 6 teams depending upon team experience.
