Group user statistics

More stats is always nice, imo.

Your post may belong more in the Bugs/Suggestions discussions category.

Sent, Received, and Value Difference are all based on the face value amount of the gifts instead of the real CV amount.

That is correct - They use regular CV and not real CV.

Gift Difference is just the number at the front of Sent minus the number at the front of Received, but what those numbers actually represent doesn't seem to be explained anywhere.

That is true. As for Value Difference, it is a user's in-group Sent CV minus Received CV (NOT real CV).

No where does it say the actual number of gifts someone has sent or received

The only time Sent and Received gift counts deviate from whatever might be considered "actual" is if someone posts a giveaway to multiple groups, at which point the Sent gift count is divided among the number of groups (0.5 count = 2 groups, 0.3 = 3 groups, etc). Such gift count division does not appear to happen with Received gifts.

...real CV amount is also not shown anywhere. Why? It feels like these statistics were implemented without any care for how they might be used by group admins.

I support your SG suggestion of making more group stats available through the site, but my educated guess at answering your question is that many groups have such unique rules that there are very few (if any) additional stats that SG could provide that would be used by most groups. The most common rules or definitions of fairness relate to sent & received ratios (gift count and/or CV) and periodic mandatory giveaways. Both of these things can already be determined by periodically checking the existing Group User stats.

Every other way in which Steam groups on SG define giveaway fairness or worthiness of group membership appears to be very different.

Also, some groups either create their own tools or use existing tools such as ESGST, and SG doesn't seem to often develop stuff that other community members have developed tools for. I have personally lobbied ESGST for enhancing group related stats, and it has been great to see it become powerful over the past year for pulling more group user and group giveaway details. By cross referencing it with Steam DB and barter.vg data, you can pull stats on group giveaways' review stats and whether a game has No CV (like when previously given away by a dev).

My observation is based on some months of me reviewing other group's rules in order to start a group myself. I haven't been on SG long enough to notice any support/mod/admin response to feedback like yours regarding group stats.

About not showing RealCV on group pages - group pages were made years before cg decided to show actual sent and won CV on user profile pages. So it is not directly connected.

Don't know if there is a reason why groups were not updated as well, or how it would impact database performance (real sent CV was already calculated, so only real won CV was added).
