Lets for calculation sake say I'm working with a 55gallon tank that needs a 10% per week water change. Instead of doing 5.5 gallons at once could I do a 1.1 gallon change 5 days a week. If so I'd much rather do that.

Becuase you will end up changing a portion of the new water at the next water change. for example:
let's say i did 1 50% water change well now the tank has 50% clean water and 50% dirty water, the next day i do another 50% water change i end up removing 50% of the dirty water AND 50% of the clean water so now there is 25% of the dirty water left.
Which i could've just done 1 75% water change to equal that and used less water.
works the same for much smaller water changes.
im surprised no one brought this up in all threads of this topic this is always mentioned in the first post.
