Macro, thanks for keeping the thread on topic. I am aware of the fact that TPR and APR are not the same. I think there are two differences: One is time, the other is scale. Regarding time, I have noticed TPR lagging behind APR. In one occasion I have noticed, APR lagging behind TPR. I think it was two or three PR updates ago, but I'm not sure. Regarding scale, TPR is rumored to be logx(APR), x being a debatable number.

I don't think TPR is total scam, though. Apart from the above two differences, TPR seemed pretty consistent to me: APR update of all pages, APR factored into serps, TPR Update.

I also seem to have noticed that the PR update algo has been changed some time ago to go only so far to new, internal pages of a site, traversing deeper into a site every time PR is updated. This affected APR and TPR as well.
