Did Japanese designers believe Queen Elizabeth made 25 knots?

Did Japan choose a 26.5-knot battleship speed because it believed the Queen Elizabeth class could make about 25 knots?

That belief was one factor discussed: Japanese planners credited Queen Elizabeth with roughly 25 knots and sought an advantage over it.

Foreign design decisions depend on estimated performance as well as an opponent's official or later verified figures. Japanese discussion treated Queen Elizabeth as a roughly 25-knot ship. A 26.5-knot requirement would then create a usable margin in range control and fleet maneuver. Intelligence estimates can transmit one class's reputation into another navy's design targets even when the original ship's practical squadron speed was lower.
