Maybe Speedfreak1 has some more infos on one of the above:)…2009 Pickering got 10"08 with slightly above 2 m/s…I feel the difference btw outdoor 60 and indoor ones are due to wind and training.
For some italian guys we have slow 60 outdoor compared to indoor, due to a shift of emphasis on other training components, and, unfortunately for some, a loss of strength caused by not performing weight training for months.
