How do you guys time your hooksets?
Answer: Not very well...
As Matt and Jonathon mention above its not always a given. There can be many reasons for missed hook ups, and things can change in certain circumstances, and with different species.
A few years back I did an all night float on the Sturgeon River. I was told to "wait for the weight" which seemed easy enough, but when you hear a nice fish break the surface in the dark its hard to not pull the trigger. I ended up loosing some nice trout because I'd pull the fly away from them before they actually ate it.
Out west one year I fished the Madison and the fish are super quick, and I followed it up on the same trip with a float on the Yellowstone and the Cutts are super slow.
Fish in slow deep holes take their time as well and have what seems like all day to inspect your offering...I get twitchy sometimes in this situation. :)
Sometimes a fish may change its mind when it gets near your fly and there is something there, most often drag, which spooks them.
I have had some guides tell me to make up a short saying and force yourself to repeat it when you see a fish move to your fly...
Sometimes it might be the fly...As Matt mentioned he was using an extended body fly that may get pushed away sometimes by smaller fish...Stiff plastic tailing fibers can angle the hook away from a sipping fish.
Mike...It may be better to miss a few, at least you moved those fish to your fly. You can count them, in a way...:)
I think we all have felt your frustration at one point or another. That trip I posted recently on the Manistee I had a gorgeous trout right along side the boat and he decided not to cooperate and spit the fly back at me before we netted it.
We all should be happy to be standing in a beautiful river giving it a go...Sometimes you win and sometimes you don't. Keep practicing! Work on some mends to get that fly floating naturally and with time you will solve it...At least enough times to up your average.

Sometimes when I hook a bigger fish I give it a serious tug to make sure that hook gets embedded. You don't have to rip their lips off just drive it home a bit...
I am kind of known for the infamous "look-away" cast...I cast to a fish and watch a bird fly by only to hook a trout when I wasn't watching. My fishing friend wouldn't let me count those or the fish that hits when the fly was at the end of a float and dragging. Oops! ;)
