My table plays slow

could be the slate in my opinion. Thicker slate rolls faster.

Most diamonds have 860hr on them if it has 760 it will be like an ice skating rink all day long. check your rail bolts see if torqued to 15ft pounds no need for tighter it just creates rolls in the table sometimes from over torquing. room tempature under 74 degrees creates hard rubber rails to play stiff and not as bouncy as if warm then they speed up a lot. if cloth is installed to tight on the rails to create rough feeling rail points then rubber went be aloud to expand fully and play dead. sunlight leads to hard rail rubber from it being broken down from uv light keep table covered with a thick table cover. then rail hieght and quality of rubber and brand of table home versus a comercial table and quality of balls.

clean the balls and check in the talk to a table mechanic section and post a few pictures of the table there and we can answer you post better as im a mechanic that dabbles in cues lol
