Do more singular extensions This patch continues trend of last VLTC tuning - as measured by dubslow most of it gains was in lowering marging in calculation of singularBeta. This patch is a manual adjustment on top of it - it lowers multiplier of depth in calculation of singularBeta even further, from 2/3 to 1,5/2,5.
