Well, a "sport pattern" is, by tendency, a flat affair, so that the lane's outside areas feature a higher volume of lane conditioner. There's (much) less room for error, so that the flat shot reveals inconsistencies of any kind: hitting your marks/targets and breakpoint, speed, release changes, etc. It's like a magnifying glass, and if you are not used to such a condition, it can be VERY frustrating (and revealing, too).
My best tip from personal experience is: keep your game simple and rather avoid a big hook - minimizing error sources (e. g. for splits and other ugly leaves) is IMHO the ticket to mild success, and rather rely on your spare game than on strikes.
