Ok Larry - I've done a rough recalculation, making these allowances:
5 lenses (with VR off on the 70-200 & 200-400). 2 lenses with VR on and no TC. 2 lenses with VR on and TC on. 1 test run to establish ISO increase. 2 test runs (estimate!) aborted due to beta software errors.
Total equivalent lens runs = 12. Shutter count increase = 5,000. Clicks per lens/test run = 417.
If we halve the 417 figure (since you did two complete series of tests) it still amounts to around 200 clicks per lens.
