Well - one handed lift of a thing from goround to over ones head in two seconds is 2*BL. Drawing a bow is shorter than from ground to over ones head. It's effectively one handed though it's not easier to draw a bow with two hand than would be drawing it one handed if the other part was fixed..
but 2* BL gives only 40 LBS for average guy..
8*BL - two handed lift could be closer.
If a standard (min strenght 11) longbow is 100LBS an average guy could barely draw it fully - giving -1 to hit. ST 11 is enough for 150LBS bows with no problem then..
However GURPS bows hit max damage only at thrust+4 so the upper tolerance for longbow would be strenght 17 and for composite bow strength 15..
15 is BL 45lbs - so let's say pulling a bow to absolute maximum is BL*4 - while the min strenght is BL*8 - so 100 to 150 LBS bows would be usable fors trenght 10 to 14 for composite bows and 10 to 17 for longbows - anyone ower ST 14 is going to need a special (over 150lbs) bow to get full use off strenght with composite bows and for longbows - likely just longer arrows - well ST 18 archer would need special longbow..
So the tolerance of longbows would be pretty big - different arrows could compensate for different users.For quality troops I'd expect ST 13 to 15 with all the bonuses from perks arms strenght lifting strength etc.. Base ST 11 to begin with should not be hard to come by by just selecting big guys, two to 4 points of arm/lifting ST should be trainable pretty easily. (HPs and striking strength part would be much harder to train..)

Yup - the draw force needed to draw a non compound bow increases the longer the bow is drawn - so people with lover strength simply draw the bows a bit less. For recurve bows the draw curve is mentioned to be pretty much straight - so for straight bows it's upward rising curve.
