So, there is a new PD thing.

I tried open it, i told there is some training for new advanced tools. Ok so let me see that …

“Density curves” could use a bit of info on what we are talking about here.

“Look for a hump on the curve, called a “shoulder”” I guess they mean a local optimum. From the looks of the sample, it can be both up and down and sideways, but really need some info on this as I am just purely guessing as this point.

“Shoulders can indicate a cluster where you can draw a gate” What is a gate?

So, ignore the graphs, draw usual boxes 94% accuracy.

““Valleys” can also indicate a point to draw a gate.” What is gate again?

If a gate is these boxes that come where you click, how are you supposed to make 3 graphs with just 3 clicks on sample 1?

But well, ignoring the graphs, 99% accuracy.

“Tails are when the curve slopes down more gradually” now I am still entirely guessing here, but that also counts sideways? What is a gate again? Assuming the gate is the box, where on the very long valleys and tails should I place the box?

Sample 3, knowing there needs to be 5 helps, but how are you to determine if its the left or right coloumn that has 3?

“When a high density peak is followed by a less dense tail” Guessing a peak is a local optimum, previously called shoulder, since they use two words I may be off here. But I just don’t see what else. Since these are density graphs, aren’t everything on both sides of a peak always less dense? Do they mean we are supposed to see a difference in line thickness or something?

(I don’t know if I finished the training yet, just stopping caring to type questions.)
