Optimum for what???? Is that best rate or best angle???

Best rate of climb.

It is actually because of the fixed pitch propeller but lets not get ahead of ourselves and get all confused on the correct principles for climbing speeds.

This is not propeller related. There are performance tests with Rotol propellers show that the same applies to Hurricanes or Spitfires with CSP.
