Pen Pressure not capturing light strokes

[Joe-Cooks]

The pen pressure works but does'nt seem to capture the lighter strokes the way I would imagine. For example if I am in photoshop and have a brush that is set to 5 pixels I would expect the lightest strokes to produce 1 pixel lines and the heaviest strokes to produce 5 pixel lines. Unfortunately the amount of pressure it takes to get the computer to capture a stroke makes it impossible to get those thinner lines. I've attached an image to illustrate my point. 

Look at the first 2 strokes in the image above, the thinnest part of the stroke is still pretty round and thick. Now look at the third stroke, I was able to get that line to taper but I had to draw it really fast (not practical) which leads me to believe the computer has the capability to do what I want but for some reason I am unable to do it in a controlled manner. As you can see in the photoshop brush settings my minumum diameter for the brush is set to 0% which should allow light strokes to produce very thin lines.

I'm hoping someone else has dealt with this before. As of right now I'm unsure if this is a flaw in the technology, a flaw in my machine or just something I'm overlooking but any help would be greatly appreciated. If this is just the way the technology works then I would suggest HP release something that allows users to adjust the sensitivity so we can define how much pressure input is required to record a light / heavy stroke. I think the surface does this with some sort of pressure curve. Another thought I had was that it may have something to do with palm rejection? I'm not sure if my hand on the screen is somehow interferring.

So I downloaded a program called LazyNezumi  which gave me the pen control I was looking for across all applications. It's honestly kind of frustrating because it proves the laptop is capable of doing what I want but the options just arent available. I wish hp would at least incorporate some basic settings for pen control. Makes me feel like the art community is an after thought where as the surface and macbook pro seem to cater to creatives (I dont own either so I can't really make an honest comparison). The spectre is an amazing piece of technology but hp would need to care about the needs of artists to make it an effective tool for us. As of rght now I am very happy after installing lazynezumi although a little irritated that I needed to buy a $30 application to make my $2000 laptop function the way I want.
