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.

I can do that. I will get on that this weekend.

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.
