seems negligible to my non-physics eyes though - the length difference is small compared to the overall length of the bow and there is little weight out at the limb tips to aid this effect ?

its so to do with the % difference in effect.
longer working limbs on longer bows have longer strings, all this extra length means a 1/4" delay in release on the bottom finger or top, makes less effect on the stress levels on a less stressed longer limb.
take a extream example, lets take a 80" longbow. and a 50" where the whole bow is the limb. Then the string is 2" shorter then the bow and lets look at half the bow as the other half does the same.
40+39=79"
vs
25+24=49"
That is the amount of moving parts to make the 28" of draw. lets say you pull the bottom limb 1/4" more than the top.
the 1/4 is considerable more of a jump towards stack on a short bow, than the long bow, so the stress levels will make the limbs work more differently in the short bow than the long, making the bow less balanced for the same amout of error...
its getting late for that kind of explanaition, hope it came out ok...
thats stressing the shorter bow
