I would agree that this stuff is more "interesting" than "conclusive".

Some data is easy to draw conclusions from, but it's usually already obvious. For example, lure category and month. No surprises here:

But I guess even this stuff is tightly related to the specific lakes we fish. Swimbaits wouldn't be as dominant if we were fishing lakes without trout. February wouldn't be as good if we lived in North Dakota.

However, the fun thing about fishing logs is you don't need a lot of fish for it to be statistically significant. If you see in your logs that you caught 5 fish over 5 lbs from lake X in late January when the water clarity was 4-6 feet on swimbaits in 4 feet of water, chances are very good you can go do it again.
