Oops! You're right, I was using the value 513.2mm (which is the top tube from miter to miter, not center to center). Using the 545.5 C-C top tube number, the effective top tube is 558.0mm.
Crap! I got Stack calculation wrong, too! (But the reach should be right)
Stack should be 547.5 x sine( 78 - 73 ) + 532.5mm x sine( 73 ) = 557.0mm
Reach should be 547.5mm x cosine ( 78 - 73 ) - 532.5mm x cosine( 73 ) = 389.7mm
