chrisb1, it is well-known on this site that you are the greatest admirer and connoisseur of Shelton. You quote him extensively.
Above you wrote that Shelton supervised "50,000 plus fasts in all states of disease and ill health". I don't believe it. This number of fasts is impossible for one individual to supervise. Below is a quick rundown.
Assuming an average fast of 10 days (a conservative estimate) and an active practice of 40 years (another conservative estimate, I would rather guess it at 30 -- but maybe you know how long Shelton actually practiced?), here are the numbers:
10 * 50,000 = 500,000 fast-days to supervise,
divided by 40 years of practice,
this gives us 12,500 fast-days per year to supervise,
divided by 365 days in a year,
this gives us 34 people to supervise EACH and EVERY single day during 40 years, without a break.
Only old fasting clinics in Russia (with max of 30-40 beds in a ward) could come close; and they were run by numerous personnel, both doctors and nurses.
And you claim that Shelton did it single-handedly?
