Yes, I'm aware of the 5% you mention.

~ 80% of my printed pages are 75/100% coverage and in plain text so I 
think I may be able to (reasonably) compare output between what I 
accounted for with the OEM cartdrige that came with the M2020W and 
the refill.

The refill service said 1000 pages, which I obviously take with a 
large grain of salt but I will be comparing my output against itself 
with the only difference being the OEM cartdrige vis a vis the 
refilled one.

The OEM one (which HP barely fills), went down for the count at ~361 
pages so I just have to compare that with the refill's output.

Yes, but that is for the original OEM filled cartdrige which can cost 
as much as what I actually paid for the printer.

It reported 532 printed pages and the difference with the CUPS log 
(361) is due to a problem I had with the first page_log file which I 
deleted.

In any case, the refilled cartdrige needs a chip to do that as well 
as printing via wireless, which I don't fancy.

I did not have it installed as it was a substantial increase in the 
refill service price.

Thanks a lot for your input.

Cheers,
