The QUADRUPED field guidelines. This is how I have been painting QUAD fields for a long time. The field should be as flat as possible,

and we use the best fields available. The field should not have any drop from one end to the other end. If the field is not perfectly flat, it should
not drop more than one yard across the 100-yd length (one meter/100-meter length) for any new records to be considered for the record books.
