Okay the 30 day booster itself may be a waste, it may not given that the only way to get them is the merc pack and the cost of the merc pack is doubled in value by the 40K AUR you get plus all the other goodies.
But just to clarify the daily cap is 27,200/day and 40,800/day with active booster
Passive boost is 24,000/day and 36,000 with passive booster.

https://forums.dust514.com/default.aspx?g=posts&m=458111#post458111Its the same thread just figured ill save you the trouble of scrolling down 3 post since ppl are weird and will read only the first one and not look at the second one otherwise.
So having boosters does in fact increase the amount of SP you can earn in a day.
As to the cost of a 30 day booster well we dont know what it is in AURUM but look at this way.
A 1 day booster costs 2K AUR, 3 day costs 3,500 and 7 day cost 7K.
There isnt a hourly booster so given your options the most economical booster to purchase is the 7 day. Meaning a month will cost you 28K AUR= $12 US. For $19.99 US you get 40K AUR(5 7day booster and 5k AUR leftover btw) which is face value PLUS a 30 day booster and FUSED LOCUS NADEs and other stuff which you can probably sell on the secondary market when it hits. So in essence a single merc pack can net you 2months and 1 7day worth of boosters at a 25% discount and net you additional swag that you can later use or sell.
So even though you may feel they are worthless given the alternative choice of buying 1 day or 7 day boosters, they are not inherently worthless, oh also by the same logic a 30 day booster is also worhtless after 2-4 days if you hit the 0 mark when it was weekly cap, so really the argument doesnt hold much validity if that is your reference point for "worth."
Also given that SP gain only really matter for the first 4-5M SP im not saying that its P2W but it is pay to get ahead, if only for the short term but in the long term it is not P2W.
Edit- Before anyone say oh you trust CCP's numbers they lied to us about daily cap when chromosome hit, well tell you what prove to me that you have earned more than 51,200 SP in a day without any boosters and ill eat my words. But you will need to time that very carefully off the daily server maintainence, so it would be easier to prove that you earned more than 27,200 without active boost simpy create a new character spend as much of the SP you start with if you can, 0 it out if possible and then see what your final SP is when you first starting reaching 50 SP.
