Even without us knowing her Bounty, the fact that she is a high ranking member, a SC, would be proof enough to know she is strong. Which is simple potrayal. Oven and Daifuku were mentioned together with the SC's, Perospero and Compote to be Monsters. They were clearly potrayed above anybody else not mentioned. Tamago and Pekoms were not. Which you wanted to put even above Oven and Daifuku.
Even tho Pedro defeated Tamago 2-3 times, while he got overwhelmed by both Oven and Perospero easily.
Then let me ask you what did Perosero did to justify his 700mil. bounty? He didn't do anything either, but overhelm Pedro like Oven did - yet you don't seem to have a problem with Perospero having a 700mil. bounty but you don't see Oven and Daifuku having bounties more than 300mil.
