IMO, there is no right answer; no single universal bench height formula. The proper bench height has much to do with what type of work you intend to do at the bench and even which tools. If one want to optimize bench height for planing, it's going to be pretty low for sawing and chisel work and vice versa. If you use wooden planes, an even lower height would be ideal but now makes it less well suited for saw and chisel work. Some height in the middle might seem like a good compromise or it might seem poorly suited to all tasks.
Since I do much of the tedious rough dimensioning with machines, I've set my bench on the tall side to favor joinery type tasks. I built a moxon vice but I rarely use it except for dovetails and even then, only if they are too wide for my face vice.
