Late Rent Increase

I have a good relationship with my landlord although he's a bit lacking in places - slow response times, no notice before entry to look at stuff. Been there 10+ years. I just got a rent increase this wknd, and he's dated it rec'd October 1st for increase starting Jan 1st. I know he's late and I am within my rights to wait until February to increase rent. Should I be courteous and give him the extra money cause he's slow and means well and to keep things good between us? Or push back and make him learn the Tenant Act?
