Guideline XP for Investigation/Roleplay/Exploration Sessions: 

1 Minor Award at Average Party Level per hour of non-combat play (max Level 10/600). 

4 Minor Awards per typical 4 hour Session (max 2400). 

Substitute Major award (uncapped) where there is a major accomplishment.

Epic Awards (Level 20) DMG pg 231-232

1 Epic Boon per epic achievement. Typically 1-3 Boons per 64-page Pathfinder AP adventure (eg at middle & end), 

or 1 per 5 sessions/20 hours approximately for a level 20 adventure.

GM's notes

Theoretically I have enough material just from the Runelords & Shattered Star APs for about 5 years of play (Nov 2015-Nov 2020), even without counting supplementary material from standalone adventures & other APs, or homebrew stuff. 

With 5e level advancement tending to speed up in levels 11-17, it's possible that several high level adventures could be run with PCs at level 20, in which case I will use the 5e DMG Epic Boon rewards, where PCs get a Boon for completing an Epic task such as destroying an evil artifact, or turning back an extraplanar invasion. I reckon in practice that would typically mean 2 Boons per high level Adventure Path adventure (at ca middle & end).
