2 sq ft per hour! Come on, that's like 4-8 tiles. Once you get going,
you can easily do 10 times that much.

Actually, that's two 12 x 12 floor tiles.

Maybe in the middle of the field you're going faster, but if you account
for the true time it takes for everything--moving furniture, removing old
floor treatment, prepping the floor, setting up the saw, laying out for the
edges, mixing thinset, measuring edges and corners, sawing edges and
corners, mixing thinset again, laying again, mixing grout, spreading grout,
wiping grout, wiping grout, wiping grout again, all the clean up of trowels
and sponges and buckets and walls and yourself, putting the saw away, ...
c'mon. No fair not counting your helper's time, if you've got one.
