The unclear border between blitz and rapid

The time control blitz and rapid always had an unclear border. At FIDE, 10|0 is considered blitz. At Chess.com, 10|0 is considered rapid. Today, I will try to solve this by counting the maximum seconds/move for all time controls that matter in this subject. First, let's start by choosing the average length of games in moves. I think this is 40 moves. Let's count with this.
3|0:
(3×60)÷40= 4.5 seconds per move.
3|2:
((3×60)÷40)+2= 6.5 seconds per move.
5|0:
(5×60)÷40= 7.5 seconds per move.

Till there, we can be completely sure that we are talking about blitz. Now comes the unclear part.

5|2:
((5×60)÷40)+2= 9.5 seconds per move.
5|5:
((5×60)÷40)+5= 12.5 seconds per move.
5|5 is the longest standard blitz time control on Chess.com.
10|0:
(10×60)÷40= 15 seconds per move.
10|0 is the longest FIDE blitz time control, and the shortest standard rapid time control on Chess.com. For me, it is almost like blitz.
10|5:
((10×60)÷40)+5= 20 seconds per move.
Now this is a great jump.

After this, I think that the border is still unclear. 5|5 and 10|0 aren't blitz nor rapid. Also, I noticed that the players who play 3|0, 3|2 or 5|0 blitz are completely separate from players who play 5|2 or 5|5 blitz (or 10|0, though that counts as rapid).


And here comes the big conclusion:
The time controls from 5|2 to 10|0 should deserve a completely separate time control category. These time controls aren't blitz nor rapid.

Any thouhgts?

So that’s why almost/everything in Fide is blitz except the 90 min ones

No, in FIDE everything from 10 minutes with increment to 60 minutes is rapid.

💀🙏🏻

no, blitz is like ~5 mins

rapid is ~15 mins

classical is ~1 hour

just speaking form experience, normal time controls I've played are 15|10, 90|30 and 90 mins (I don't play blitz)

Blitz is ~ 3 min

Rapid is ~ 10 min

Classical is ~ 30 min

Bullet is ~ 1 min

Hyperbullet is ~ 1/4 min

As in in fide.. we don't have hyperbullet or bullet in fide

and 30 min is rapid in fide. usually classical is 1 hour+

No, Blitz is <10 min in FIDE, rapid is 10-60 min, and classic is 60+ min.

Anyone would notice that I wasn't talking about this? I was talking about that a new time control should be added between blitz and rapid, as 5 min-10 min doesn't feel as rapid nor as blitz.

I think that time control is rarely played tho. 10 mins is common in rapid

Some local background behind the topic:

https://www.chess.com/news/view/10-minute-chess-now-rapid-rated-bullet-ratings-increased

10 mins isn't the same as 15|10, nor the same as 5|0.

I like blitz (3 min) and rapid (15|10), but I don't like 5 min nor 10 min nor anything between them.

Correct

well done

I dislike Blitz and Bullet... it's chess with an asterisk. Same with 10/0, though less so, the shortest time control I'll play.

I like 3|0

I've never seen any player who likes 3|0 and 5|5, which are technically in the same category, nor any player who likes 15|10 and 10|0, which are technically in the same category too.

I dont like the time increment at all
