SVB and Tix priceing

Can we keep the San Van Bucks price and the Tix price a little more consistent in the skate pass. 
Why am I paying 550Tix for 25SVB and later you want 600Tix for 25SVB? Then you want 2600Tix for 75SVB the math aint mathing here? 
I'm ok if you want to charge 550Tix for 25SVB but It would make more sense to make the 75SVB for 1650Tix. 
For the Tix price I'd just suggest making a base price for all your itums and increase depending on rarity. Please fix 🙏
