Calibration is the biggest waste of time for me. Due to the almost limitless variables involved in fdm printers, doing these tests seems like a massive waste of time and filament. No offence, but you'd be far better off trying to print your object with different settings than this test. Or spending your time actually learning how to use modelling programs like max, maya, cinema4d, zbrush.....the list goes on. And then trying to print your creations to the best of your abilities.
But the main problem with fdm printers (and my experience with the ultimaker 2) are nozzle jams, as without these the printers generally print great out of the box. You calibrate the printer with the sheet of paper thing right? And you only really need to callibrate it after 4 to 5 prints if you are getting issues or are rough with removing the bed whilst taking your model off it.
If you have a problem with overhangs concentrate on solving those, but you'll waste so much time finding the right settings for each particular filament at certain temps, and layer heights that it all becomes a little pointless.
The printer is calibrated out of the box. And unless you are printing with some more exotic material like flexible metallic or transparent filament, rather than bog standard abs or pla then just playing with speed and temp and layer height is all you really need to do remembering the nozzle size thing, i.e. A factor of 0.4.
You can spend your entire life calibrating... But it wont stop the printer from jamming right before you kick your print off. Putting you back to square one!

It would be good to test! Though I think the test piece needs a lot more facets on the round parts. how can you measure the precision of the circles when they're not circles to begin with!
