I have been reading several TNs on VC where the "experts" (I have my list of those who I consider experts!

) advise us on how a 97 cab (for example) may be closed or going through a dumb phase. If the wine is one in my cellar, I go to bottlecount.com and update my "best before"/"best after" fields.
I kinda understand the interactions between the fruit, the tannins and other consituents in what makes the wine go through such a phase BUT, here's my question (and associated learning): I hear different answers (read, timelines) for different wines even if they are of the same vintage, varietal, and region.

Is there a place where we can start entering the "experts" opinions on "best before"/"best after" so when its time for me to pull a bottle, I can quickly scan their opinions ? (I recognize there will be m(w)ild disagreements, but at least we will have a variety of opinions and the reader can choose).
Or, is this simply a learn-by-mistakes exercise which I may not be qualified to pass judgement on until I go through years of tasting?
While I am at it, here are my 97 cabs/blends I am considering popping open as soon as they are ready (with my best after/best before fields) - please advise on obvious no-nos.
