Is it normal for a table to pick up speed as humidity increases? I always thought they slowed down when it got more humid. My table was normally 4 1/2 to 4 3/4 table lengths, now its about 5 1/4 tables lengths up and down. It also picked up a hop on the short rails, pretty much any speed the entire length of both short rails. It doesnt do it on the long rails. It could be dirty if that can cause it, I have not vacuumed it for around 6 weeks but it is always covered except for when I play. Thanks for looking.
