Chkdsk's percentage number meaning

I am chkdsking a hard drive with Windows 7. When it goes thru it's stages like 1 - 5 it has a percentage on the bottom line. Is this the percentage of the total chkdsk program or of just the stage that it is in? My guess is the percentage showing is the percentage that is completed by the entire chkdsk program and not the individual stages. Am I right about this?

I think that is probably correct, although I could not find any information to confirm this. Note that it may take a long time on very large hard drives.

Thanks
