They always say, this is the first report, sample again in 5000. But I just don't see reports where these particle streaks or residuals from past changes are indeed what they speculated as. I just don't know how much these events can sway variations in these reports.

My bearing wear metals have been decreasing each time. I've done three so far and I am waiting on the fourth as we speak.
OP, mine had higher lead when I bought it with 43K miles on it. My car also has a slight tick. Some times it's not noticeable, some times it is. I have 75K miles now and even though my analyses are looking better, I still feel like "the damage has been done". I will probably change the bearings soon.
