How 'bout 42, then?

More seriously: since I don't want `t` to be equivalent to the maximum
depth, there are 2 numbers to be "remembered".  In order to follow the
same convention as add-function, I'd really much prefer to keep 100 as
the maximum.  As for the value corresponding to `t`, I'm definitely not
wedded to 90, it could be any value in the ]0,100[ interval.
66?  50?  10?  99?  π?

Will do.

I think that'd be more trouble than it's worth.
But I'll warn against using 100 (or -100), in the doc.
