I just might as there is no such thing as shaker speed in itself, only shaker alpha. There are shaker speeds for weight, configuration and normal acceleration. Shaker activation is not just unconfirmed but for the time being not mentioned at all and as NGs have no other alerting systems apart from shaker I suspect that such might be the case on -500 so "Stall stall stall" belongs among speculation. Anyway:
