Are you sure that the caution will even show?
Years ago I had a caution for S2 Assault (worse than it sounds!) and it didnt show on 3 record checks I had during that time - one of them was actually a 'more in depth' one (I forget the technical name for it) and it wasnt on that one either.
Dont forget that after 5 yrs cautions are spent and dont need to be declared.
