I think you sent me that link another time Rum.
I'm happy to use that if others would, but it looks extremely busy and still only has one place for Damage, so if you had a "Boss" who was being attacked, it would still be a single number such as -46
in the damage row if they were hit more times in a round then once ...
I would perhaps suggest that we leave the damage at whatever minus value it is at, and in the end column, as well as the last round something took damage (or healing), you could put the damage give beside it ...
Something like: 2/24 28D, 2/16 14H D
-- meaning Damaged or Healed.
I like PB's idea of adding to the formula, but know that some idiot (read DM at 0030 in the morning) will most likely stuff that up and add / subtract directly to the number, hence wiping out every one else's good work
I am as you all know, open to suggestions and will go with whatever is the general consensus
