this event is not RNG-ish but its difficult to.
you need 35800 RSP to get all rewards, div by 14 days left you have to get around 2557 RSP a day. div 24h you need 106 RSP an hour.
you get 2 raid points an hour but its impossible to spend all raid points a day so lets say you can make use of 24 raid points a day if you're very active. that makes around 215 RSP per hour, so for every raid point you use you should at least earn ~110 RSP. low bosses drop around 50 or 60 RSP, so you have to wait until you see a big one with lvl 80 or higher to get some RSP...

edit:
lol, i just got 109 RSP for a lvl90 "di eter" raid boss...
