I have landed on 100m airplane modeler grass strip with full flaps on 50knots smooth landing approach and stopped on 80 metres without butterflies in my stomach. Tall story ? No, single, with 60 litres of gas and a good concentration on it. Take-off less than those 100 metres.
With no headwind, using the speeds recommended in the POH, and at or above 50ft /15m at each end of the runway? (Plus you clearly weren't at MTOW).
