I think so too...

As mentioned the two clients I test against misbehaves with this, 
running at 116-117 bpm instead of 112.

Same with seq24 and ardour (although ardour seems to sending "midi time 
code".

Note the following is not to bash ardour, just a simple observation. As 
stated I know nothing about midi clock I'm just fooling around!

I tried syncing renoise with ardour and that didn't work out that well 
(ardour master to compare with when my script was master). They seem to 
stay in sync, but they have the downbeat different places. After 
stop/start the downbeats are messed up in a new way.

Maybe it's all just a shitty old protocol that is finally being replaced 
by stuff like jack transport (that works very reliable, actually 
precisely between renoise and ardour).

Maybe I should stop thinking so much and just hack away something that 
works for exactly my purpose (I only need to sync with sooperlooper), 
however wrong (according to the standard) it is.

Still, I'd be interrested in any input, though...
