One could have wrestlebacks after the quarterfinals, only. If you're a regional #4 drawing the top #1 in the state in round one of semistate, to have been the #4 coming out of regionals, you will have had to have lost twice at Regionals. There are at least 3 ahead of you, and then someone outside your regional is the "ringer" death draw. So that wrestler does not have a case, really, to claim to be one of the best 4 at semi-state. But, those who lose in round 2--the current "ticket" round, they easily could be a top 5 wrestler in the state, lose to a top 3 wrestler in regionals, and then draw the number 1 in the state in the ticket round. I have literally watched the number 3 in a given class go down to the number 1 in regionals, and draw the number 2 in the ticket round and be out of state. THIS is the problem that the wrestlebacks are intended to solve, NOT taking away the upsets, which will always happen, it seems completely disingenuous to say "well then they weren't the best on this particular day", while the left out top 5 wrestler watches someone they've beaten 3 times this year in the grand march reveling in the whole pageantry that is "State". The IHSAA seems not to understand what "Going to State" is to a wrestler. It is a defining moment...a lifetime of work...and this is what COULD be corrected if we had an open mind. So I say, wrestlebacks after round 2, but NOT after round 1.
As for time, I agree that is a concern. I'm not sure how all the semi-states look, but at New Castle we spend every year at LEAST one hour in "breaks". This year we had 3, totaling about 90 minutes or so. The New Castle "breaks" are becoming legendary. That is easily enough time to put in a single wrestle back round.
