These are the equations I used for weight capacities (not satisfied with the ludicrous ones in the pack)
---STR x CON = Maximum Lift / Load
---½ Maximum Lift/Load = Light Load
---Maximum Lift/Load x5 = Shove/Heave
LONG VERSION ==========================================================================================================
One thing that bothered me, and two of my players agreed was kind of striking, is how strong a STR 10 person apparently is. According to the pack I have, a STR 10 person can lift 500lbs off the ground. Even halving that for over-head, that is an average joe lifting 250lbs over their head. Most athletes don’t make it past 260, and even with the heartier lives of medieval peoples, one assumes that if they were ‘hearty men of the land,’ or whatever, they’d be str 12; maybe even 14 if they were the big tough lumberjack kind.
Point is STR 10 = average joe, and the average man cannot get 500lbs off of the ground, let alone over their heads. And lugging around 100lbs as a ‘light load,’ to use the a phrase; is equally improbable. We’re talking about a world where children would be moving as much weight as a grown athlete.
If the average adult male can lift ~ 120lbs, and a strength-based athlete can do around 250, then my math dictates that their STR value should be multiplied by 14 to get their Heavy Lift/Load. For the amount that they can carry around as their Light Load (as I prefer to call it), ½ their Heavy Lift/Load value. Then, for pushing and dragging, as both actions are considerably easier than actually lifting something, quadruple (or maybe even quintuple) the amount.
The only problem there was that you had the mid-range working out fine, but then the higher Scores were just beginning to break the notions of a ‘strong man.’ In order to get proper results the modifier would have to increase at a rate as well; and in figuring that rate I started, stopped, realized how much math that was going to be, and then had one idea before I gave up: Multiply STR x CON to get Maximum Load. From there, ½ their Max Load = their Light Load, and x5 their Max Load = their Push/Drag.
