They're called FLOORS!

[Saseal]

I'll call them turns until people call them floors in general.

I initially didn't know what to call them so I went with 'Alex T1, T2, T3, T4'.... then I thought "that can be confusing and I'm extremely lazy. 'A1, A2, A3, A4?'..."

Seeing this debate and the demand to call them Floors, a.) Now I know what to refer to them as, b.) the demand/'omgwtfs' to call them floors just makes me want to rebel >_>
