So this is actually a house rule we implemented after playing the rules wrong for years and things working smoothly enough to never know anything was off.
Only planetary scale armour counts as x10 personal scale, not the wounds themselves. This allows things like missile launchers and lightsabers to be actually decent at fighting off Imperial walkers and lightly armoured aircraft like TIE Fighters.
The only noticeable downside is it makes civilian vehicles and speederbikes super fragile. If this is an issue just set everything to have minimum armour of 1 and you've solved that issue completely. It allows things like a blaster rifle to do enough to destroy it if you're a good shot/modded it/rolled well but still is having its damaged reduced by 10.
