I would start with getting the effective top tube dimension (or just plain top tube for the Reacto?) as close as possible. You might want to try a more detailed fit calculator like the one at the competitive cyclist website and focus on getting close on the top tube dimension.

You should double check your cycling inseam measurement. It is not your pants inseam. The fit calculator at competitive cyclist gives you one way to measure it. Using a 1" thick book and a wall works just as well, you don't need the level that competitive cyclist uses.

If I had to guess, I would think the bike in the photo is a bit small for you. However, I can't really be sure from a single photo, and also you may have to adjust saddle for correct setback. It is more important for you to try riding a couple of sizes (I would try a 52cm and 54cm) and seeing how the bikes feel in real use. If your torso is fairly long (which your measurements seem to indicate), the 50cm frame with the 535mm top tube would probably be a bit cramped/small.
