10:1 is 12m shares and 1.40 area. 20:1 maybe possible but thats on the high side that this stock is allowed to be. Over 2 and people can margin Sint. Better to RS to 1.40 then drive it to 2.80 for the holders to profit and then drive it back down.
Do you completely disregard book value to come up with your ratios? Do you ignore the 1.4m they got in grant funds? Not sure how and when those funds are dispersed but that impacts companies book value.
In 2019 when Sintx did a 30:1 RS they had about 2-3m coh. So 30:1 seems unlikely.
