I usually take around 5-15 minutes to do a little research before answering questions in proz.com. By using this method, I can provide some reference link and add up my confidence level, although sometimes I jumped in too early with a conclusion and receive a lot of "disagree" comments ^^
About this topic, I have to admit that I only search for "broken in" phrase in Google search engine and try to match the best explanation for compressor/machinary context, thus my confidence level is only 1.
I think the confidence level should reflect your personal degree of certainty that what you are proposing is suitable. I also have to say that sometimes I post because I feel sure that what I'm proposing is correct but later have second thoughts and we are probably all in the same boat on this. A very interesting subject and would love to hear some feedback from fellow Prozians :)
