The share of 99.26%of thecombinedaccelerations fulfil theconditiona≤4m/s2 which isdepictedas thegreycircle infig.4.6(a). The limitwaschosenwithrespect tosimplificationnumber3 of the linear STM on page 97. The large amount of the measurements fulfilling this limit shows that nearly all accelerations are within the linear range of the tyre characteristics, see linear area near the origin in fig. B.2(a). 54
