There's also some unknown factor at play, too. Sometimes for no good reason, the same offering yields a different time away. There are three possible explanations:
1) There is an unknown point multiplier that fluctuates, which makes smaller offerings worth more at random times
2) The thresholds for certain tiers fluctuate at random times
3) The away time (and therefore) the tier of reward is not 'constant.' Meaning any given gift can provide a range of times with the published times having a very high probability (something like 95% for the 'base' time and some small percentage chance of others at random)
My money is on option 3.
