My 1E-7 figure is based on a 6cm growth in a week.
That's 'in the ballpark' for a rainy week.

A quick visit to the store (and shed) shows the width of
the smallest trimmers is about 22cm (gain some there).
(I'll post summary spec's when I get a chance).

I've cut the number of 'mowable hours' to 8 per day
on a rule of thumb "two hours charging for one hour work".

That gives me figures in the 100 - 300 square meter range.

(Come to think of it I really have no idea how big my yard is.)

I agree.
Time is more of a problem than originally anticipated.

Seems very reasonable.
Shoot for "average yard" capability;
live with "smallish yard" capability;
Large yard folks need to increase the number of mowbots.
