If you use the --rri task then Osmsois will do all this for you - find 
out which minutely deltas are required, load them, and out drops a nice 
and shiny single custom-built .osc file that has exactly the changes you 
need.

You are right in so far as Osmosis cannot mix daily/hourly/minutely 
diffs, if will always get the minutely if that's what you configure, 
thus incurring a slight overhead because of the larger number of HTTP 
requests, but that's all.
