Had none for the first 14yrs on my licence, then started working in IT mobile support (from Leeds, mainly to Hull or around Yorkshire area, doing around 50k miles per year) and got 6pts in 11 months. SP30 - 46 in a 40 (200yds from where road changes from 40 to 50) and SP50 - 97 on the m'way (was lucky as the copper had me at 117mhp but got blocked coming after me, pulled me and offered me a day in court or 3pts/£60 combo - said he didn't want to spend a day court and gave me the option). That was 4/5yrs ago now, so none valid for totting up purposes.
