Should ½ chess have it's own catogory?

It's bullet.

i agree that 1minute is different to 1/2 minute chess. you need just be aggressive in lowertime. and press your opponent in opening till endgame. but you just need a super fast connection in 1/2 game chess. because you will defeating on time. But that is an option to play 1/2 or play 1+0 time control for the lichess users to gain more points.

Don't introduce a new category, because then I would feel even more diminished. I already have difficulties to maintain a reasonable looking bullet rating, but with great difficulty in 1m+0s I can force myself do so. I tried some 1/2m+0s games, and I have no chance. Here factors unrelated to chess take over like the sheer speed with which you can move the mouse. The same is true for 0m+1s.

If in the end you introduce such a category, call it 'Video game'.

Keeping number of categories low is very good approach, but still, 1/2 is way less chess than mouse clicking battle, so moving it into separate category like Halfbullet or Semibullet makes perfect sense as well.

Multi-medium rating chess system: (A well rounded player)
Maybe a solution is to have one general rating that does a medium of all your ratings (It would have to take into consideration the number of games played). With a multi-medium rating score, there would be little impact being outstanding or a beginner in any one variant or speed chess game. A player would have to be outstanding in all the variants and time controls to truly reach a generalised master level.

To do this we would have to restart all bullet ratings but it is an idea

#14 That's the whole point Of bullet but it isn't only mouseclicking you need a very good chess Instinct for it. And if one doesn't fancy bullet they play blitz.

Chess instinct is good, but if I think of a move, but can't execute it on the board with the required speed, or if I try to do it fast and I misclick and execute the wrong move ( how often this has happened to me ... ) then I'm finished.

Physical execution speed and accuracy is a necessary condition to play under 1m+0s.

Not a sufficient condition, since your moves still have to make sense, but a necessary condition. One that begins to dominate.

Then I am for a vote to remove the 30 second bullet, it is plain white sillyness

But then one could argue that all variants should have diffrent catogories as you can play those in super bullet
