How often the sync is triggered?

I am also very interested to know more details about the frequency of sync.

I find it shockingly unreliable. If, for example, I delete a favourite from my browser at the office computer, then a few hours later when I arrive home, I find nothing has syned. I find that this unreliability ultimately contributes to a traffic jam where things just end up being over-written and lost.

I currently find myself in a situation where sync seems to have completely broken and I can't get it working again. In an effort to stabilize and 'reset' the syncing conflicts, I have turned off and signed out of all browsers, then re-enabled sync on only one browser. Though this has had no effect.

I don't know if I'm just working too fast for Sync to keep up, or what's going on. But perhaps if I better understand the Sync service, I can work within its limitations.
