It’s nice to hear that everyone else also experiences the elevation differences – I was cheap last year and cut plywood into 8″ strips to maximize the amount of boards per sheet, but it only gave me about an inch of ice on the opposite side. So will obviously need to increase the height of my boards this year to compensate so I can get a larger sheet.
Another question for you experts, do you typically try to flood the rink over a couple of nights instead of flooding it all in one night? I also had that problem where one side took awhile to freeze up as it was 6″-8″ deep and was thinking it may make more sense to do it over a couple nights… May not be a big deal though.
