'bytes transferred in Chrome's network tab

How should I read the following from Chrome's Network tab (in developer tools):

enter image description here

My guess is: 1114 requests, 2.9 MB transferred over the network, the remaining till 5.2 MB (i.e. 5.2 - 2.9 = 2.3 MB) were found in the browser's cache and did not result in any kind of network activity whatsoever.
