STU Turbo Car Weights?

[Knestis]

Front wheel drive cars may reduce their minimum weight by 5%.
Front wheel drive cars with a strut type front suspension may
reduce their minimum weight by an additional 2.5%.

So does that mean that, if one is racing an FWD car w/struts, they take the restrictor table weight and subtract 5%, then subtract 2.5% of the resulting weight...

OR

...take the table weight and subtract 3%...??
