google pr update?

[cranki]

Is there a rule of thumb how often google revisits a site for updates relating to the pagerank?

e.g.:
pr 1 - every 2 weeks
pr 10 - every day

[mufas]

PR1 - every year

Noo sorry.

PR8 - 2x per week

[Tex Willer]

so google visits itself every day

well it depends.. but all I know the higher it is (and the more updates you have), the often it visits your site
