I own the clock linked to above.

For some time now, I have been trying to figure out how to program the settings I want. From experimentation, I know that the clock has 9 presets: the first couple are absolute time, 6-8 are fischer time, and number 9 is something like byo-yomi but with only one bonus period. I think options 4-5 are bronstein time (time delay).

Does anyone know if this clock is capable of normal Japanese byo-yomi settings with multiple periods? If so, how do I program that?

I have this clock and sadly, it is capable of Japanese Byo-yomi only with ONE period. I have not yet seen a Go clock that is capable of multiple Byo-yomi periods. I do not understand why - seems both desirable and easy to implement.

Ing clocks support multiple byo-yomi periods. However, I am not familiar with any other digital clocks, so I can't say if any others do.

I don't see the advantage of japanese byo-yomi over time-delay. And time delay has the advantage that if you go 1 second over your period you lose only one second and not a whole period.

To be honest, a digital timer needs one and only one setting to be functionally perfect, and that is fischer time.

However, people frequently request that we play byo-yomi because that's what everyone is familiar with on KGS.

Time delay is the standard from my chess playing days and I agree that it is better than byo-yomi, though not for the reasons you list.

Anyway, one last question: what is the standard time setting for weiqi tournaments in China? I believe this clock must be preset for that?

byo yomi or sudden death.

Is that byo-yomi with a single period? Example: 60 minutes main time + 1 x 1 min?

Absolute time for go is ludicrous, especially with the availability of modern digital timers.

Hmm, just found the korean Nongshim Cup is single period byo yomi.

The Chronos definitely supports multiple byo-yomi periods, as well as just about every other reasonable timing system that I've run into. (That includes a Scrabble mode in which you lose points when you go over your allotted time.)

The funny thing is, I actually have one of those clocks, but I never cared about any other setting than Fischer time.

I've never seen a go clock that didn't.

The Meijinsen (which I have) supports multiple byo-yomi periods (1-99 periods of 1-60 seconds), as well as Canadian time, Fischer time, sudden death, and a Xiang-qi time mode.
