Thumbs up for this comment on the determination of XP for similar methods used for different CR monsters.We can then suppose a number of methods for the party to get past the monster - they could both be bribed with the wine, distracted by an illusion in the same way, persuaded or deceived with the same difficulty (it'd be reasonable that the Giant is harder to intimidate, but we could imagine a slightly bolder Ogre or more cowardly Giant if we like). The point is that the difficulty of getting past the monster is identical in all ways aside from combat.
So, if we assume that the system we are using gives xp rewards for getting past the monster (as all 3+ editions do) then how much should we award? Should it be dependant on the method chosen? Should we have a Combat CR and a non-Combat CR? (4e sort of does this - we might class getting past the monster without fighting as a lower level Encounter and use that to determine the appropriate DCs and rewards, it's not really well spelled out in the text though)
This is a fine point to consider for tables using XP.
