Overpay not calculated, spartan's price is out of date, no proof to support low or high range, with overpay included, would make the modest 3.05 buds

Thx for sharing the sale but there are a few things wrong with your price.

The price for the spartan is slightly outdated and needs to be updated first (with a normal or mini suggestion).

And then you still need to consider unusual overpay for it, so if the price is 4-5, you take the average *0.9 (~4.5*0.9 = ~4) - the bud he added = we get 3 buds for the modest, perfectly in the current range (actually it would be better to use this sale to price the spartan).
