It's all about the bays.

[Old Mod]

That's how I was taught to do large commercial floors.
I still use the same principle today when ever I'm dealing with irregular sized tiles, handmade or otherwise.
I apply the same technique on walls too, just even out the joints in each individual bay and it gives a more than acceptable finish over the entire area.

when I first started way back in '86 as a labourer then improver we used to do very large floors, 10's of 1000's of m2 floors, brewery's, milk plants, factory's. Biggest I remember was Walls ice-cream Gloucester (I think)
Anyway, we used the same principle, but we laid in sand and cement and ran ribs down a to drains about 10 mts apart with the high spot half way between them.
once ribs set out it was just a matter of pulling a line between them and bedding a couple of courses at a time.
all pointed in Epoxy.

That's awesome. Bet that straight edge doesn't come out much for floors these days.
