The maximum slope b=rise/run compatible with this is b_max = (314 mm/3m)/F_L = .105/F_L ~ 0.005 for F_L = 20, https://www.astmfree.com/wp-content/uploads/2018/01/E-115-M.pdf https://www.astmfree.com/wp-content/uploads/2018/01/E-115-M.... which corresponds to 0.005 radians = 0.3 degrees. Projects like roller rinks and warehouses that use air pallets require more level floors, but typically only by a factor of 2 .
