Clinically having used both FSWT and RPW with positive outcomes for MTSS I can provide clinical support for Tim's comments
A couple of papers you may wish to read to provide guidance on energy intensities:
Rompe et al. 2010 Am J Sports Med, Vol. 38, No. 1, pp. 125-132
Cohort study, level of evidence 3
94 patients – running athletes
47 RPW group – 3 weekly sessions
47 matched control group – rest, ice, home exercise protocol
Pain score: significantly greater pain reduction at 1m – 4m – 15m follow-up in RPW group
Degree of recovery: significantly higher success rates at 1m – 4m – 15m follow-up in RPW group
Return to pre-injury sports level at 15m: 40 RPW patients vs. 22 control patients

Prospective observational controlled trial.
Storz Duolith SD1 Subjects: 42 athletes with MTSS, from two different sports medicine departments. Methods: Patients from one hospital were treated with a graded running programme Patients from the other hospital were treated with the same graded running programme and focused ESWT (5 sessions in 9 weeks). EFD increased over the sessions from 0.10 to 0.30 J/cm² - number of shocks was 1000 in the first session and 1500 in the 2nd to 5th session. Outcome : main outcome measure was Time to full recovery (the endpoint was being able to run 18 min consecutively without pain at a fixed intensity
Significantly faster return to full recovery was obtained when adding ESWT to a graded running programme.
Hope this helps Cliff
