Hello All,
I've notice the amount of completed tasks reported by my host is always much higher than total reported on website.

For example, at time of posting this my host stats are saying Total Completed: 6,647 but the website is saying:
All (4701) · In progress (1033) · Validation pending (52) · Validation inconclusive (0) · Valid (3607) · Invalid (0) · Error (9)

My host: https://boinc.multi-pool.info/latinsquares//results.php?hostid=50852

Is this correct? Or am I misunderstanding how tasks are being reported?

Results on the project websites are typically purged. Otherwise some people would have hundreds of millions of tasks. It's too much for the servers to keep track of. The real results are saved but the task info is purged.

Thanks for the clarification.
