You seem like a knowledageable chap, and clearly you have first hand experience, but do you mind if I ask for your source of information?
I always thought (no source) that it was 30mph over the limit that got you into proper trouble with a possible ban, and consequently normally sit with the cruise control at 98/99mph GPS, safe in the (apparently ignorant) knowledge that I'd only get 3 points / £60. In the light of the proper quoted information from reputable websites that we've seen here and in DD's recent thread, rather than the usual pub talk, it's made me think enough to consider change.
When i was pulled for doing 107, the copper informed me that he has to refer anything more than 25mph over the limit or over for the consideration of the magistrates.
At exactly 96, if you've got a clean license its possible they may not refer you to the magistrates at all, and issue you 3 points and £60. The key thing here is
consideration
Its not a hard and fast rule that 96 = court and a ban. The only hard and fast rule is that if get caught doing 95 or less, they cant refer you to the magistrate unless they want to report you for consideration of Dangerous or Careless driving.
Assuming you had 6 points, and got caught doing 96, you probably would go to court. Once there, your fate is entirely up to the magistrate. Bug One got caught doing 116 and was banned for 28 days, I was caught doing 107 and was banned for 28 days, but Lopez was caught doing 100 + and got off with a large fine and no points, as loosing his license meant loosing his job.
If you can proove you need your license for your job, you can escape a ban.
You need to make sure that your GPS speed is less than 96. To be absolutely sure, i would probably be doing about a 93 indicated, so that would be about 90 GPS.
heres a link to the ACPO guidlines that mention the 26mph rule for referral a magistrate. Only exception is 30mph where its more than 19mph over the limit, and in a 20 limit its more than 14mph the limit that gets you sent to court.
