17														51.5	<-- average ratio between max & min
18		Sizes in KB (1 KB = 1024 bytes)
19		Undercount	of weight
20		Overcount	of weight
21		Chrome is reference weight because it always gets it right
22		For each test tool, the whiter the column the better
23	Notes
24	Safari	Lists payload size, uncompressed, doesn't include response headers
25	Chrome	Lists over-the-air size of assets + response headers
26	Firefox	Lists payload size, uncompressed, doesn't include response headers
27	Internet Explorer	Lists payload size, uncompressed, includes response headers
28	Firefox (Firebug)	Seems to list over-the-air size of payload, without response headers
29	Firefox (Web Developer Tools)	Lists payload size, uncompressed, doesn't include response headers
30	WebPageTest	Lists payload size, uncompressed, doesn't include response headers but adds favicon.ico (1456 bytes)
31	sitetest.io	Lists payload size, uncompressed, doesn't include response headers but adds favicon.ico (1456 bytes)
32	page-weight.js is a tool we wrote for testing purposes
33
34	Chrome and Chrome Canary produced identical results and hence are not listed separately
35	Firefox and Firefox Developer Edition produced identical resuls and hence are not listed separately
