xpGain = TotalTime/5

TotalTime = (Object's mass)/(Foraging level)

In human terms, all objects give you equally scaling xp so assuming a perfect scenario you're always leveling up at the same rate.

If all you care about is the xp gain, you're much better off just foraging the largest object you can since it will be closer to a perfect scenario than spamming something like sand since there is a very brief delay in between foraging smaller objects, while the larger object will calculate xp based on the entire time.
