My barefoot inseam measures 32.5 inches, so method 2 works out to about 28.6-28.7 inches which is nearly 1/2 inch lower than the heel method. My bike is 56cm and I believe is correctly sized for me. I think the lower saddle height will work better for me based on a short test ride.
But I'm not so sure about the fore/aft saddle position yet. That seems way out of whack from the methods I've seen (including KOPS).
There are a lot of "rules of thumb" for saddle fore/aft. All of them at some time can look like no more than old folklore.
But you don't need all of them, just one that gets you started so you can get out and feel if the results are good for you.
Same goes for saddle height, though the calculations are easier and seem to be more related to the problem of pedaling. I'm pretty confident you'll find things you want to try differently after you do start doing your own optimizations. None of these rules and methods are definitive answers. We're all here just trying to help you get started, and maybe to learn something ourselves by seeing the discussion and seeing how it works out for you.
