Forum:Ultimate Offering and Infinite Flip Summons

Ok I have looked at the rulings on "Ultimate Offering" >>> and I really focused on this ruling

"You can activate the effect of a face-up "Ultimate Offering" during your Main Phase even if you have not done a Normal Summon yet this turn."

Ok so if I decide to use it "Ultimate Offering" effect 5 times to set 5 monsters (which will cost you 2500 life points) before conducting my own given normal summon....would I be able to flip summon all of them that turn since i haven't normal summon or set a monster without using "Ultimate Offering" effect???
