Quick Question: What Exactly Triggers Reduced CV for Games? (Only Bundles?)

As far as I can tell, reduced or no value can happen for multiple reasons, most prominently is a game becomes more available either through a bundle, or a large public facing giveaway such as Alienware Arena or Pantaloon, there are also low effort games with high value so those reduced because they game the system. Keep in mind all of this happens manually so there might be exceptions because they weren't caught.
The FAQ briefly mentions a game being bundled then getting reduced value shortly afterwards.

Reduced CV happens when a game gets bundled or heavily discounted in some store, I think 95% off when compared to the base price in the US regardless of in which region (so even if the deep discount is only available in just one country), but I believe it has to be a legit store to count so no grey market resellers.
No CV happens when the game has been free somewhere as long as the number of keys was large enough, can't remember the exact number tho. Games that have only been free directly through Steam don't count since there's no way to gift those.

Because of the price if it reaches ~95% off on steam or even in grey markets it will get reduced CV (sometimes it can happen with 90% games I have heard because, for example, Russia has low price even without discount and if some "exploit" it can be reduced).. If the game is given away (at least 1000 I guess copies) it will be marked as no cv probably.
At least these are the things I have heard.

Not all bundles have their games put on the reduced CV list. It is determined by the discount of the games. There was never an official set amount and it was up to the discretion of the support member that adds the games to the list, but years ago it was believed to be 95%. If a game was on sale for 95% off or more, it would get put on the reduced CV list, this goes for bundles and regular sales. You also have to take into account foreign currencies after being converted to US dollars. So, a game might be 85 or 90% off, but once you take the Russian discounted price (or any other country) and convert that to US dollars, if that price is at least 95% off the US retail, it will get put on the reduced list. I'm not sure if they are still using 95% or if they have gone a bit less.

As for games being added to the 0 CV list. In the past, only games that were given away for free somewhere were added to that list from the date of the free promotion. It doesn't matter if a game was 99% off, it would only get added to the reduced CV list unless it was actually free somewhere. Now, it seems like a lot of games are being added to the 0 CV list that haven't been free. I'm not sure how this is being determined, but it seems like very highly discounted games are having their CV removed. I know this is done for the fake games that are sold for pennies and then have their price increased to high amounts, like $50-200, which is understandable, but I don't know why this is happening with real games many years after the sales.
