I too have had quite a low efficiency when mining on this pool.
I've got a variety of systems contributing, some of them are Windows and some of them are OSX. It seems that all of the OSX systems have horrid efficiency, while all of the Windows ones are working great.
The OSX systems are running poclbm-mod.py. Here is what I see:

I've never seen efficiency higher than 5% so far.
In all OSX examples I am using the following command line to launch the miners:
python poclbm-mod.py --user=1PC5hWLgpmLZie7Mqvt2GiU5zrSQkzWVJP --pass=blahblah -o pool.bitcoin.dashjr.org -p 8337 -d 0
Are the above symptoms a result of a mistake on my part? Or is it something beyond my control?
For reference my bitcoin address is 1PC5hWLgpmLZie7Mqvt2GiU5zrSQkzWVJP.
Thanks for any help,

I'm running Windows 7 with a Quadro FX 3700M Video card (in a M6400 Dell Laptop), so my invalid or stale blocks aren't due to Linux or OSX...
