The passage around this formula

Define each species’ offensive rating against another as the best same-type-attack-bonus multiplier its own types can produce against the target’s typing — the maximum, over its one or two types t , of the product of the chart’s multiplier for t against each of the target’s defending types. Call this E(i,j) : species i ’s best type-advantage multiplier attacking species j . It rewards nothing but typing — no coverage moves, no items, no stats — by design, because typing is the one variable the chart alone can price.
