On these engines it doesn't make a jot of difference about the throttle, you've already removed it all when you took the inlet off.
It'll spin a bit quicker with the other plugs out but I doubt it'll show much of an increase in compression.
I'd say that's defo on the low side but not catastrophicly. But someone like @bloke knows better.
