TA4 is an all Ducati track day on July 25th (I think - unfortunately I can't go). There, you will find everybody is courteous and will not carve you up (don't read courteous as SLOW).
Weeksy is refering to another mixed track day on July 4th where he will be able to get amongst some Dukes on his Gixer race bike and hence the talk of annihilating people.
I wouldn't worry if I were you.
