I am a newbe to the razor sharpening game ane have found that every razor is different and there is no set rule to sharpening a razor.
All my razors are from ebay and I have a good collection of junk but that is sometimes handy to try new things. ( I also have some really good blades as well)
I have found that I start with a finer stone rather than going to a course stone from the start. Working backwards has really been enlightening to some point.
Something you might try is if in question, mark the bevel with a shaprie and make a few passes and see what the wear pattern is and you might get some insight into what you need to do next.
If yuo can afford a microscope ...get one...you will never regrete it.
Here is a link to a good one that isn't too expensive for what you get
