iirc, that's true. But we don't have much choice there.
the thing would be to be sure that this specific value is hard coded,
and so that we can safely ignore it.

yep, the -1 values were inherited from my very first USB devs.
since these are mapped to HID values (in the UPS) and are in fact
timers, -1 means that these are inactive. So the right values for the
ups.delay.* are the real values (default or settings) used for the
various shutdown sequences.
Now, the previous ones (used for ups.delay.*) have moved to
ups.timer.* which makes more sense.

this is due to the rework on the shutdown handling in usbhid-ups.
there were some wrong things that have been addressed. the result is
that some new commands appeared. The "load" notion is linked to the
devices wired on the UPS' output (and which sums up in the ups.load
I hope to have answered your questions.

NUT really needs some advert and promotion...
I would also be glad to see you promoting the FLOSS/NUT friendly
