I am enquiring about the apprentice allowance

As all my systems are newspaper based, I am wondering what to do when an apprentice is riding. I have never taken this into account before...but
My reason is one particular (new) system relies on 2k difference from last start
Yesterday at Rosehill R4-6 Flying Alpha, is in paper at 55k with a (a2)
Do I take off the 2 making it 53k? or is it already off.
Last start (20th may) 51.5 (a)
Where as the system today had Tamworth R5-1 57k (a)
Last start 57.5 (no a)
