I think it's just a matter of how aggressively they're feeding. If they're just nipping at the bait, they are just barely hooked. Sometimes we hook several fish in their gill plates. That tells me they're just being mean and swatting at the bait wanting to cripple it. By the solar tables, which some folks swear by, there's only a couple of hours in a day when the fish are actively feeding. The jury's still out on solar tables in my book but something seems to turn them on or off all over the lake at the same times.
