That's correct. The more testers we have, the earlier the RT version 
under development will become stable. However, there is no guarantee, 
and sometimes - for example now - tip may even contain unreleased 
material that runs just for a couple of days on a limited number of 
machines.

Alternatively, if you do not have the time to test software under 
development and you would like to use it for production purposes, you 
may want to use the "Latest Stable" PREEMPT_RT release. This "Latest 
Stable" version underwent heavy testing on a number of different 
machines, and latency plots and long-term latency recording results are 
available in all cases. The "Latest Stable" version is announced here -> 
osadl.org/Latest-Stable, the related QA data are available here -> 
osadl.org/QA.

Hope this helps,
Carsten.
