Pasted strop: too rough?

[Payne]

.5 micron chromium oxide came prepasted on the back of my leather strop. I only strop on it occasionally, for about 20 round trips, to freshen the edge of my razor. The past couple of times I've done it, my razor has seemed rougher when I shave and has ripped up my face pretty good. After str8 shaving for nearly 3 months, I feel pretty confident that it's not my stropping technique that's too blame. I strop with a very light touch and am careful to not roll the edge. Also, I don't think it's my shaving technique, as I've been getting very comfortable, close shaves lately.

Anyway, I'm wondering whether the surface that the paste is on is too rough and uneven and is actually dulling the blade. Check out the photos here and let me know what you think. As you can see, quite a few nubs have been raised on it. It still feels fairly soft and suede-like, but is uneven.

Also, from some threads I've seen here by JoshEarl, it seems that there may be too much paste on the strop.

Any input you have would be greatly appreciated.
