How to interpret my List1 v List 2 results?

tharsos

I would appreciate some small comment about my results.
I used the feature Advanced->Tools->Show Stats->List1 v List 2 (Identified/Verified)

Here is what I got about RSS:

RSS-blloggs...................: 0000000039/----------
RSS-blogcollector.............: 0000000054/----------
RSS-blogdigger................: 0000000019/0000000019 => 100.00%
RSS-blogdire..................: 0000000048/----------
RSS-bloggernity...............: 0000000063/----------
RSS-blogmetrics...............: 0000000029/0000000010 => 34.48%
RSS-britblog..................: 0000000022/0000000026 => 84.62%
RSS-feedcat...................: 0000000052/0000000001 => 1.92%
RSS-feedgy....................: 0000000053/----------
RSS-feedplex..................: 0000000033/0000000010 => 30.30%
RSS-fybersearch...............: 0000000041/0000000009 => 21.95%
RSS-globeofblogs..............: 0000000050/----------
RSS-lsblogs...................: 0000000055/----------
RSS-oobdoo....................: 0000000035/0000000004 => 11.43%
RSS-plazoo....................: 0000000049/0000000047 => 95.92%
RSS-rssmicro..................: 0000000056/----------
RSS-rssmix....................: 0000000033/0000000034 => 97.06%
RSS-rssmotron.................: 0000000044/----------
RSS-rssnetwork................: 0000000043/0000000021 => 48.84%
RSS-rsstop10..................: 0000000019/0000000023 => 82.61%
RSS-twingly...................: 0000000023/0000000018 => 78.26%
RSS-xmeta.....................: 0000000014/----------

I noticed that some of the results are like this: 0000000014/---------- or 0000000044/---------- or 0000000063/----------
Would that mean that the success rate is 0% and that I should stop submitting to this type of engine or that simply there is no way to verify some types of engines?

Thanks

Yes your examples means that the success rate is 0%. I would never build RSS in the first place, but I would like more data than this normally before disabling an engine.
