Okay, this will likely come up in the future, so let me address something that is probably a quirk of style. When I ask anyone a question about how a bonus was arrived at - any bonus or modifier - I would like some sort of breakdown to be presented in answer to my question, if that breakdown is not already on your sheet (ideally, everything would be broken down on your sheet.) For example, "AC is 30: 10/base 5/nat 5/armor 5/dex." This sort of thing is easily examined and verified - and easily adjusted (anyone can see that the AC 30 in the example above would become AC 25 flat-footed without having to look anywhere else in the sheet.)
If you answer my question in general terms without providing an exact breakdown (for example, "I'm sure my AC is 30"), the matter is not fully resolved. This means that I have to again go back and look at your sheet to add things together. Unfortunately, my time is limited, so time spent double-checking is time that is not spent doing things like forwarding the plot.
I have updated the RG opening post to indicate that sheets should offer this breakdown to speed things up. I recognize that asking for this kind of detail can be annoying for people not used to doing things this way, but the alternative is that every time I look at a sheet, I wind up recalculating unattributed things. For what it's worth, I meticulously break down all bonuses on all NPC sheets (saves, skills, AC, and other types when applicable, such as CL and DC boosts.) It might not be a big deal if we had the typical four players, but it is a problem with ten. Thanks for your understanding.
