If you belong to a pool another way of looking at your wins is that for every 1.75XCH you get from the pool, you should have a win (of course, that is on average). So, if you have 2 or 3 XCH already, maybe you have just some bad luck. If you are pushing 6 or 8, you need to start to worry.
How many stales your pool reports?
By the way, you should not have those “Last farming event was XYZ seconds ago.” I am also using ChiaDog, but I only see those when I shut down chia (i.e., logs stop). However, I am not sure what those lines indicate. Those don’t reflect harvester activity / drive access (I think), rather farmer is either not getting challenges, or not sending responses. Maybe you could change pool for a couple of hours, and check whether you still have those lines.
Also, your plotting times really suck comparing to your box raw power. Although, I don’t know what k-values you generate.
Did you check the power draw of that box? One k32 plot should take about 100-150W.
