Why is 10-min considered Rapid?

I'm sure this has been discussed a lot, but it still doesn't make sense to me. A 10-min game feels just like 5|5, which counts as Blitz. I know the rationale is that an average game takes ~40 moves, and so a 10-min game gives you more time per move than 5|5. But you can't play so that you run out of time after 40 moves. A game might take 60 moves, or 80, and you have to stay on the safe side. To me it feels like you have to play a 10-min game just like you would a 5|5 game, maybe even faster.
In contrast, a 10-min game feels very different from a 30-min game, where you really have plenty of time to think. So again, drawing the line between 10-min and 5|5 seems weird to me, but I'm curious what others think.

That has the details for when it was changed.

Yes, thanks! I've seen that. But I would still maintain my point...
In fact I also think 3|0 should be Bullet rather than Blitz, again more similar to 2|1 than 3|2. 
The psychological effect of having no extra time per move is more significant to me than how much time you get per 40 moves.

i agree.

No clue

I think it could be considered rapid however 30 min games + would be a different control but *shrugs im not complaining

Thanks everybody! I know this is unlikely to produce another change, but anyway. I don't care so much about the naming, but IMHO 5|5 & 10|0 should be in the same bag, and 15|10 & 30|0 is another category (you can call it SlowBrain... for ppl like me).

In OTB chess, 10|0 is still classed as Blitz but the rating system and categories here are specific to Chess.com so they can define them however they like.

Time controls are probably shorter here because they have to be balanced with pairing time. I play exclusively 15|10 because it can often take several minutes to get paired (2000 +/- 150), longer games would make it even worse. I abandoned trying to play 30 mins.

I agree with a lot of the points here.

I am a horrid blitz and never mind bullet player, but the 5/5 is the only reason why I can maintain a blitz rating because it does resemble a 10/0 rapid game.

With rapid, I prefer 15/10 and rarely time out. 

Comparing the play of 15/10 vs 10/0 vs 5/5, I run into stronger players at 5/5 funny enough. There were times I ran into 1400 players who slid down to 1200. This means 5/5 is skewed with stronger players at the 1200 level.

With 1200 rapid, I am sensing the talent pool is fairly accurate.   

Same thing here; I'm personally simply worse at faster games. It feels much easier to play a 1500 opponent in a 30-min game than 10-min or 5|5. I don't know if it's just me (old brain...) or if the people playing 30-min are objectively weaker.

Maybe I would play 10-min if it was Blitz but like this, it would just damage my Rapid rating. 

is the 10 minutes for the whole game or per move? And is it just while you are on there or does it keep ticking away when you close the app and go do something else?

Laws of chess:
"B.1
A ‘blitz’ game is one where all the moves must be completed in a fixed time of 10 minutes or less for each player; or the allotted time plus 60 times any increment is 10 minutes or less."

So yes: 10|0 is blitz and this site erroneously considers it rapid.

10 minutes for the whole game

It keeps ticking away when you close the app (It's better to resign than just leave the game, shows respect to your opponent)

They have some obsession with fast games

a game of chess can have between 30 and 50 major moves, so playing 5/5 and 10 minutes is completely different (10 minutes is longer than 5/5)

i think less people paying attention to the 10|0, 3|0 flag will get more attention

I recently focused on 5/5 and 15/10 which helped with improvement.

I don’t see much difference with 5/5 vs 10/0 in terms of play quality.

All time controls seem much shorter otb... You can do more moves online than otb in 10+0, which could make it rapid instead of blitz...

But then, playing online and playing FIDE rated tournaments are not exactly the same, With clocks and move notations being automatic here and human reaction time affecting over-the-board games, playing 10|0 over the board feels quicker than playing 10|0 online.

Oops, I posted my post without first seeing that you have already included my point before I even came to this thread.
