of Various In-Filled Systems

¹ In 2005, grooming of wear and no wear plots occurred on 5 and 9 Aug 2005. In 2006, grooming of wear and no wear plots occurred on 23-24 Aug 2006.
² Static traction = peak amount of force (N) that is normal to the playing surface.
³ Dynamic traction = amount of force (N) to maintain linear motion of footwear/amount of force (N) that is normal to the playing surface.
4 2 August testing performed after wear simulating 96 games. 25 August testing performed after grooming of the plots on 5 and 9 August 2005. 16 August testing performed after wear simulating 108 games. 7 September testing performed after grooming of the plots on 23-24 August 2006.
