Fishing spot

Fishing spot is a "block" in which it takes various times to catch a fish depending on which quality the spot has. Fishing spots are visible when using radars, but if you're using a green radar, the spots you see aren't accurately shown.

Refresh time
Every 10 minutes (a test done on at Pinheira beach, having 3 minutes offset - 7:33, 7:43, 7:53) the fishing spots change. The offset changes (daily?) so it can be 15:35, 15:45 and so on (tested on different day at beach). The offset is shared between areas.

Fishing spot quality
If it takes 3(4?) or less seconds to catch a fish (or your float returns without fish) on a spot, it's the perfect spot. You can see the fishing spot quality by using the best radar.
