Slippage is the average fill price of a market order walking the book against the mid; the half-spread is part of it. A size between two measured points is interpolated and marked ~. Fees are each exchange's base taker tier, before volume tiers and token discounts. Exchanges that fill at an oracle price (GMX, Avantis, Jupiter) charge price impact by formula and are not modeled. RFQ exchanges (Variational) quote only $1k, $100k and $1M. The calculator runs from $1k to $5M.
