Sort:  

Every Monday (weekly), we check the delegations and recalculate and distribute 630,000 HUNT tokens based on each user's contribution.

e.g. If you delegated 27,000 SP and total SP we received from sponsors on that point of time is 270,000 SP, you'll receive 63,000 HUNT tokens (reserve)

Ok so one could delegate 100SP one week and 0 the next and 1000SP the next, and just be rewarded for that first and third week?

If you cancel the previous ones, yes (but be careful it takes one week to get your power back).
If you don't cancel the previous ones, we calculate the total amount of delegation at that point, so 3rd week will be calculated using 1100 SP

Awesome. Thank you for the info.
