Update soak results page

+ Link to methodology (instead telling readers to search there).
+ Explain low amount of test results shown.
+ Clarify that y-axis shows an estimated interval (not direct measurement).

 Soak Tests
 ==========
 
-Long duration soak tests are executed using PLRsearch algorithm. See
-methodology section for PLRsearch description.
+Long duration soak tests are executed using `PLRsearch algorithm`_.
+
+As soak tests are new, and take long time to run,
+only 6 tests were executed. From those, 4 tests encountered some caveat,
+making their results unreliable.
