Pagerank queries - the <rk> parameter

What do such figures as Rank_1:1:6 Rank_1:1:5 mean?

[selomelo]

We already know that toolbar PR is in fact an historical figure. When you query google for current PR, you get some mysterious figures such as:

Rank_1:1:6 Rank_1:1:5 Rank_1:1:4 Rank_1:1:4 Rank_1:1:5 Rank_1:1:6 Rank_1:1:5 Rank_1:1:0 Rank_1:1:1 Rank_1:1:5 Rank_1:1:2 Rank_1:1:3 Rank_1:1:0 Rank_1:1:0 Rank_1:1:3

These figures are for a site that has a current toolbar of PR4.

I searched the web for an explanation, but failed to get a good one.

Is there any idea as to what all these magical numbers mean?

rkhare, I'd support that; but it's just a feeling, nothing I could "prove." I also believe that what we had seen as RK-values indeed WAS something like future TBPR, and that it had even been used for ranking purposes the past few weeks (live PR). Nevertheless it might also be the case that a complete recalculation may take place over the easter weekend, with all surprises normally attached to such "updates"; who knows.

>hiding it somewhere else.

presumably a four or five letter-parameter like 'info:' or 'site:'. But I don't regard the whole thing worth a "brute force attack." Cui bono? We didn't even know what to do with the info presented by these XML-files.

I think both the <rk> parameter and this discussion are now history. Thread is locked before we start wandering too far afield.
