What is average time one should be able to hold bow at full draw without shaking? Let's assume we are elk hunting and forget about situations you might be in. I know the longer the better but what would most elk hunters want to be able to have as a legite time?

Way too many variables. An elk can come up on you pretty quick and give you an opportunity to draw and keep coming for a very quick shot. Other times you see them hang up after you have drawn and they can stand there for a long time. I would try to shoot for a minute if you can. You may have to hold it longer than that or just let down and try getting on another elk if you can't hold it or are shaking too bad to make a good shot.

I have managed 1 minute and 40 seconds without shaking. Of course, the more I practice the less time I can hold during my sets. Hope to be at 2 minutes and 30 seconds.
