Actual frame sizes Cervelo SLC-SL

Hi,
Anyone out there know the actual center to center and center to top measurements on the Cervelo SLC-SL in 54 and 56?
My saddle height is about 72.5- Is that too low for the 56?
Cervelo only lists standover height and the do seem low for the listed size

looks like TT and Stack are both listed on the website. FWIW when in doubt I’d go with the smaller size

Still looking for actual measurements.
