why specify 13MB?

[rajan.mba]

Instead of the standard disclaimer for Qt app - 'This content may require 13 MB download...' has any one tried 'This content uses smart installer & will install only needed component?'
I find that smart installer generally installs just 6MB component in a non-Qt mobile. 13 MB is never installed even for apps which use pretty much all capabilities. Why should we specify 13MB at all - why can't we just say 'Uses smart installer' ?

Stating the maximum data amount gives some indication to the user how much it might cost. If you don't state an actual number, the user cannot know whether it means a 1KB, 100KB, 1MB or 10MB or 1GB download. If the typical download is 6MB or 10MB or 13MB, I don't know. Only Nokia can tell us why they think 13MB is the magic number.

Probably for legal reasons. 13MB is the worst possible case
