What will be the downlaod size of windows 10?

[Windows Central Question]

My windows update under control panel is downloading windows 10 which shows a download size of 2699.1 MB and as per the data usage the update download exceeds 3gb but the stats is shown as 30 per cent completed.
When will this be completed . Is the file size beyond 2699.1 or is there something wrong might happening .
