I did get it repaired (seals changed) and then followed it with the fps test. Some points were against conventional wisdom of testing -
1. It was open air on terrace - hence susceptible to wind
2. It was open air on terrace - hence susceptible to bright sunshine
3. It was hand held (not in vise) - though for fps it ought not matter
4. The target was almost 3' above the ground level - not the typical 140-145 cm
The groupings didn't vary that much. Truthfully, the question of "grouping" has popped up post-fps. Remember 3 well-placed hosts all landed in #10.

So while on one hand I am happy that I have finally broken the "85" jinx - now "yeh dil maange more".


[Editing/ Adding this (Oct 25, 2011) after going through an article in Pyramid Air by Tom Gaylord. He alludes to *huge* difference in fps recorded when lighting changes. Think the article is the series on how he restores Diana 27. Now he quotes phenomenal leap from 250+ fps through 650+ fps or so simply by changing the position of his AR vis-a-vis his chrono ! Now considering, dynamic positioning of onlookers on the terrace, may be some fps recorded would have fluctuated due to that reason. Next time I shall do the fps testing under more "controlled" environs. Till then the 40-Fluctuation is anybody's guess.

[Editing this (Oct 29, 2011) - Recorded the fps today under more "controlled" environs at Savarkar Smarak Range. Similar chrono brought by fantumfan2003 was used and a high wattage bulb was held by me above it to enable the chrono to operate error-free under ambient conditions. The shooter (fantumfan2003) sat on a chair and no other movement was around. This time RWS R-10 (AP) pellets were used and the fps recorded - 495 (-4), 502 (+3), 498 (-1), 503 (+4), 499 giving mean of 499.4 (or 149.82 m/s) which brought it matching to the FWB suggested mps of 150 m/s. So
