Caught speeding but actual speed not listed on form

[clanadam]

I was caught near Tyndrum, Scotland on Tuesday night - was stopped doing 80 in a 60  :o

Only thing was they didn't write the actual speed on the ticket - it just says "Ride at  mph in 60mph limit".

Now could I make things worse by fighting it or just take it on the chin...? Licence is was clean so no big deal to have 3 points unless it's a clear invalid ticket and a no-brainer to contest!

Anyone got experience of incorrectly filled out tickets (especially in Scotland)?
