I would like to up this thread because I don't have a clear understanding of where a delineation between CPV and GRV lies. I have several scenarios all of which I assume to be GRVs but since they involve both players writing down incorrect life totals it could be read as a CPV since life total is status info and this would be incorrectly representing status info. In these no player is cheating, assume they are just not paying attention/had a brainfart or something.

1) AP attacks with two 2/2 bears. NAP: ‘No blocks. Take 3?’ AP: ‘OK, you’re at 17.'
2) AP attacks with Crackling Drake and has 1 instant in their graveyard and 1 instant in exile. AP: ‘Take 1’ NAP: OK, take 1.' SPEC: ‘No, it’s 2, it counts cards in exile too.' AP and NAP after checking what the card does: ‘Yes, thank you. Take 2.’
3) AP casts a Shock targeting NAP and says ‘ Shock. Take 3.’ NAP at 20 life writes down 17 life. When a judge intervenes they both admit that they were thinking about Lightning Strike for some reason.
4) AP reveals Status//Statue to Dark Confidant's trigger and writes down that they lose 1 life. A judge intervenes and AP explains that they thought they have to choose one of the two answers so they chose the lesser one.
5) AP reveals Status//Statue to Dark Confidant's trigger and writes down that they lose 6 life. When a judge intervenes they explain that they miscalculated CMC (4+1=6).
6) AP reveals Status//Statue to Dark Confidant's Trigger but forgets to lose life.

I don't think scenarios 4 and 6 can be conceived as a CPV under any circumstances but I am open to all ideas.

Arman, this thread is over a year old. The definition of CPV has changed since it was started.

I'd suggest checking out the entry for CPV in the annotated IPG: https://blogs.magicjudges.org/rules/ipg3-7/

Locked this thread due to necro status to avoid confusion.
