Input value of sizing

Hi,

Please inform me about sizing of BI4.1 server.

Is there reference of the complexity of the Webi report which becomes an input value of sizing (high,midle,low.)?

Is there a threshold which becomes the following reference?

<High>

* On 1 report, 10 seats (tab).

* On 1 report, a chart is more than 10.

Regards,

Michiko
