Bandwidth Usage vs Web Stats or FTP Statistics

[nethubonline]

Hi all,

In report of a domain, there are "Bandwidth Usage", "Web Stats" & "FTP Statistics", and we can check HTTP, FTP, POP & SMTP in "Bandwidth Usage". However I confuse that the monthly traffic in "Web Stats" does not always match HTTP in "Bandwidth Usage", and "FTP Statistics" also does not match FTP in "Bandwidth Usage".

Anyone know the reason? And which one is accurate?
