Tracking is not an exactr science, not from any company.
If you take a snapshot in time and say "Wow thats way off" you're being pretty short sighted, if an extended period is off then you can worry a bit.
Buut thankfully theres shipping data every quarter from the big three so you can be assure that the overall discrepancy shown here is really minimal!
