Mycustomer is worth 500 dollars.... and KPM is not worth that much more. The majority of the bonus is based on budgeted script count (minus controls and narcs). If you are bringing in 0.5 percent above, why should the company give you more?
My store was 5 percent over in >4200 store too... AND we met total MCE, and KPM. Each of my staff got 5k and I got 10k. (About 5.5k after tax). The funny part? I didn't have to bust my ass.... I did fill all OTCs as scripts, did compounding for magic mouth washes, and busted my chops over PAs and doctor phone calls.
This year, it is based on SOS. I think you will do better although I have not seen the bonus structure yet.
