I just played a game with Byo Yomi 30s + 5×10s the average move length was under 5 seconds. However it was registered as a live game instead of a blitz. Is it a bug?
In the following thread it is explained that the average move should be under 12 seconds for it to be categorized as blitz:
This is a known issue. These games are currently being improperly categorized as live in the back end.
"time_control_parameters": "{\"system\": \"byoyomi\", \"speed\": \"live\", \"main_time\": 30, \"period_time\": 10, \"periods\": 5, \"pause_on_weekends\": false, \"time_control\": \"byoyomi\"}",
Given the small number of games this affects and the fact that it’s mostly cosmetic, I wouldn’t expect to see a fix in the immediate future. It really just depends on when this ever makes its way to the top of the long list of things that need attention. 
I posted, but I’m digging deeper, I see that Ruby’s PR implies what you are all saying is true. I had a very different impression, so it needs a closer look.
Currently when blitz games are created with 30s main time and 5x10s byo-yomi the API assigns a speed of “live”. This includes the automatic sitewide blitz tournaments (at least 19x19, not sure about other sizes).
I updated the PR I linked with a quick and dirty work-around, but I’m not sure that it will be approved. Ideally this would be fixed in the back end.
So they start off “Blitz” and end up coming back “Live” eh?
I agree, this should be fixed in the back end - you can create rather slow blitz games and very fast Live ones.
Just noticed it’s still like that actually (19x19), 2 mins main time and 5x10s byo-yomi counted as live in the game history.
Yeah, the pull request wasn’t merged. We have to wait for a fix in the back end.
Just saying, for me everything below 30s byoyomi is blitz with the quality of my connection…
I wonder if @moderators would want to merge the new thread into the old one? It’s the same issue

Thanks @AdamR! -ben
When I use the blitz quickmatch button with fischer time in the preferences (30s +10s per move up to 1 minute) the games get counted in the “normal” live category but not in the blitz category. Is this intended?
Old known issue, didn’t get enough complaints to be considered as urgent is my guess.
OK, well here’s another complaint. This is really annoying! I have played loads of “blitz” games but my blitz rating is unset because they have all been counted as live. This is skewing my live rating as I play worse on blitz. So anyone wanting to see how well I play live or blitz will see misleading information in my rating breakdown by time settings, thus leading to a kind of unintentional sandbagging under live time settings.
It seems the fix for this is relatively simple - just move the threshold between live and blitz. But where to move to? The obvious place is the maximum time settings available under the blitz heading, which is about 5m+5x10s IIRC. This is still very fast, resulting in a 19x19 game that takes less than 25 mins. That way, all blitz games are counted as blitz games, most live games with usual (~30s/move ~ 1hr total) time settings will be counted as live and the only discrepancy will be very fast “live” games being counted as blitz. However, it seems easier to accept a very fast live game being counted as blitz, than it is to accept a game specifically set up as blitz being counted as live.
It got complaints, it got a fix, but apparently resurfaced. (Source: the thread I posted in my first comment and the PR linked in that thread)
I see there’s no issue open on GitHub, might be worth reporting there. (github issue here: Blitz games displaying live icon · Issue #1174 · online-go/online-go.com · GitHub). Or moving this topic into “bug reports” category.
Edit: clarify that the PR also has relevant info
Didn’t read any fix just a pull request on github.
Did you look at the comments on the pull request?

Ok I finally tracked this down on the backend I think, they should be in sync now. It’s not retro-active though unfortunately.
A no thanks I stayed in the forum threads
it apparently wasn’t fixed
dragon-devourer has games:
February 28, 2021 “1 minute main time, followed by 5 10 seconds periods” - counted as live
…
March 6, 2021 “increments by 10 seconds per move up to a maximum of 1 minute” - counted as live
