Frame size
The frame sizes are skewed in the table above and are based on C-T (Center to Top) to make things a little interesting which is .67 of inseam, so if you are using this table you will need to measure off the "A1" measurement in the diagram above, which allows for 15mm of tube above top tube centre. If you want to run centre to centre you can use a calculation of Inseam x 0.65. Inseams toward the low end of the scale have size recommendations slightly smaller than what the strict ".67 * Inseam" formula would suggest. While longer inseams have sizes slightly larger than what the formula would recommend. The mountain bike table is adjusted back 10-12mm to allow for more stand over height clearance.
