If you were to lay out the exact scenario to experts, i.e. gagged TA, 3 Billion AS, 28 Million Class B equal to 2.8 Billion Class A, the overwhelming majority of them would say the OS is near 3 Billion. maybe 100 out of 100.
Especially if you added that those AS numbers were reached after 4 increases in the AS, for no apparent reason, (especially the Class B shares) unless there was a need for "headroom" caused by an increase in the OS. If the OS was as claimed, (350mm -722mm) even the first increase would have been unnecessary
M&M have never been shy about releasing the most minimal positive hype. If the 10K was positive, it would have been filed by now.
