Yeah...I think that in the emulators, the hoppers are permanently set to full, and so in theory, all money would be going 'over the back'
I've just had a £160 win within £15 on a £25JP machine and it didn't run out [in the emulator]
So....to answer your question.....you know if coins are dropping because AFAIK they always are
