I have a similar inseam and my saddle height (680.5 on your drawing) is over 700mm. I won't say how much over, because my position is a bit higher than the standard saddle height formulas would suggest. On RattleCad this is important, because the seat tube angle changes as a result of placing your saddle at the desired height and setback. In other words, as you raise the saddle, it also goes further back and RattleCad will make the seat tube angle steeper to keep the desired amount of setback.
As for the standover, it just stood out to me as the drawing shows the frame being 10.26mm over your set value. If that height works on your other frames, its not a problem.
