So the ticket was reduced (Code R), which means that if you take it to trial, the ticket would be amended to the original speed recorded (whatever it was he/she told you). Be aware that 1-49 over hold the same bearing as insurance is concerned, the only difference is 1) points (if you have a lot on your record like me, you want to avoid all as possible, before you hit your suspension), and fine.
Also, this offence carries 3 demerit points. If you were doing more than 29 over, that would be 4 points. If you have a G2, if you receive a charge for 4 points or more, your license will be suspended for 30 days.
As well, if you were clocked more than 50 over, they will retract the speeding ticket and amend it to stunt driving (Which is far more worse than a speeding ticket).
I think I covered all potential risks of going to trial here. If none of these apply to you, I would recommend you requesting disclosure ASAP, and prepare for your trial. It's never too late to request disclosure, however, if you get an adjournment, the delay may be put against you. If one of these do, I would suggest paying the ticket.
