it does not matter for compression test. you could have a 30 gallon tank connected to the injector hole. you are not measuring the Compression ratio, you are measuring how much air is being pressurized accross several piston strokes and how much is leaking out to get a total pressure reading.
it would matter for a ratio of bdc displacement to TDC displacement, but that is not what a compression test is for.
