Yeast Ratio

Hi guys, got a question about ratio of yeast.

I am making a hard cider, similar to the aplfwein recipe, one gallon.

I used an entire pack of yeast for this (bakers yeast) and let it ferment for a week. Turned out great. I am now doing it again using the same yeast as well as another gallon using wine yeast. The question is this: since I used an entire packet on one gallon, is this helping quicken the fermentation process?

If I expand to 5 gallons would I use 5 packs of yeast?

Thanks

I'm not sure how much yeast is in a packet of baker's yeast, but five packets would almost certainly be excessive. There's some debate about proper pitching rates for ciders, but I think 1g per gallon is a good starting place.
