jevco rating information on insurance contract/certificate > years lic.

this might be different per insurance provider, but my question pertains to jevco. on the 'rating information' section of the insurance contract/certificate, where it says your name, status, years lic, if you are the primary driver, driver training etc etc, in the years lic field, what is the value supposed to be? i'm assuming this is supposed to be the number of years you've been licenced(?!) or something else.

1) does this apply for both m and g licence?
2) does it actually state the number of years you've been licenced?
3) or is it an actual rating/insurance provider code? (ie: 1 = no good licence rating, 2 = so so, 3 = good, 4 = excellent, 5 = super excellent etc).
4) something completely different?!

thanks.

i'll also be calling them later to clarify.
