"Could do better"

Just had my repeat prescription medication renewed. Single bottle of eye drops provided so I have to return every 28 days for another prescription. If I am perfect and make no mistakes, which is highly unlikely, you may believe that all is just about OK. The bottle according to the pharmacist should have 20 drops per ml, or 100 drops per 5ml bottle. The internet suggests even fewer drops per bottle. The GP clearly expects me to be perfect, never to fail on any eye drops, always miss a few drops contrary to what the hospital demand, and achieve over 112 drops per bottle. I am so pleased about their confidence in me.
