But the OP does need to find out for certain. I do agree with this.....
and the OP needs to have one edge of that book against a wall or something vertical and the top edge pulled snug into the crotch.
Method I learned was while barefoot or in socks, stand on a hard floor, use a wood dowel with a slot for a tape measure, place tape end into slot, pull dowel up into crotch, have somebody look at what the metric measurement is on the floor. Did that, showed 83 cm, which is about what it showed maybe 20 years ago when I first did it.
In any event, a 2nd and longer ride with saddle at 73 cm, no knee pain, height felt just fine. Will keep riding at this height and wait and see,
