Weak Arms (Half Body ST)

Weak Arms (Half Body ST) is a 5-point disadvantage found on Shell-Tech 5.
This is based on the -25% limitation for Extra Arm(s). Assuming a base value of 10 points per arm, it saves 2.5 points per arm to have them 50% less ST. That adds up to -5 for a 2-armed being.
A 1-armed being would have to round -2.5 cost "up" to -2, saving fewer points.
An interesting house rule might be to treat this like a leveled quirk:
*-1 for -10% to ST
*-2 for -20% to ST
*-3 for -30% to ST
*-4 for -40% to ST
This of course, doesn't work out too well for merely 1 arm because it would need to be -1 per -20% to ST. This could perhaps more fairly allow them to only take -40% to ST for a -2 point disadvantage, or let them take -3 for -60%.
This linear progression doesn't match well for the other version, which would be called Weak Arms (Quarter Body ST) which is based on the -50% limitation. That would be worth -10 for 2 arms, and dividing -75% into -1 quirk increments results in -15 per -2 or 7.5% per which would require rounding.
It works a bit easier if you consider the additional -25% loss in ST to come in "-1% per -1%" increments (still linear).
Another option would be applying -25% per -50%, but that's -50% of the previous 50% established by the first tier of Weak.
