Hello, this discussion is a direct son of the "hinting and font rendering". I've decided to split because recently more and more poeple giving feedback were being confused by the title but at the end of the day the discussion has been changed for a redrawn and readjustment of the whole typeface.
this being said, i'm kinda anxious so... i couldn't wait to finish karen cheng's book and make a in depth review so i'm going on the go,, i read and readjust. Right now i'm on the Upper-case section of the book.
mixing together my previous knowledge and the one that karen gave me a was able to perform more adjustments and try to fix the bearing of the glyhps i already re-done it three times and i can see that some árts of the spacing are bad.
So i ask for help with these new issues and doubts:
1° i'm using karen's recomendation for leading of using n as a reference and distribuiting between 50-50% or 49-51% of the interior space on the n in both sides but in my case things didin't gone right the space is just extremely loose in my opinion.
2° Capitals stroke thickness, observing other typefaces i've noted that capitals stroke and in general thicker between 6 to 12% thicker when compared to the lower-case but in my opinion my capitals are just too thick, and right now i don't know if it's pure bias or a true observastion.
3° overall quality of the drawings, i made some adjustments for color, stroke consistency and overall neutrality but tbh i feel so insicure to say that i rached anything meaningful.
thank you in advance!

This one is my project, i've reduced the bearing compared to the one taught by karen but i can see it as extremely loose still, and please note the difference between upper and lower case.

This is a sample of Neue Montreal by PangramPangram, i'm using it as a refernce for texture and color, also studying proportions and tricks but i have no intention to copy any of the forms.



and tbh, making this post, i posted the same image of my project two tines thinking that the second one was neue montral and i tought that the capitals were great and the texture was better but then i realised that was mine... i don't even know what to say!

And yes, I think your capitals are a bit too heavy in comparison to the lowercase.
my target is a display typeface with a few weights and slanted romans that in the future i can expand.
Since you want to design a display font you probably want the left side bearing of the /n to bei nearer to 25%. Then follow the next steps suggested by Karen Cheng. To find the optimal value you should variate this process and compare "nnonoo".
It is not necessary, but I personally prefer if the side bearings of a symmetric /o are equal (but this can be done by a general shift of the lowercase at the end of the spacing process).
Europa, for instance, is their “Helvetica”.
I don’t know whether the sidebearings are differently conceived, other than being more tightly “tracked”.
I’ve designed several serif typefaces in which the metrics and kerning are quite different for text and display, but have never done that for a sans serif.
One of his gratests works was a brand identity to a bank called "Itau" in pure helvetica, also he produced a printed brand guidelines that was never published or made publicaly available but probably set in helvetica ou univers (he was a "helvetica" guy)
So my inspiration comes from this story and the fact that Max Bill one of his teachers and a huge influence to him, also the man who helped him to bring ULM curriculum to Brazil got a homage typeface, Sequel Sans made by OGJ Type Design...
so i'm just bringing together my passion for helvetica like typefaces, a little bit of imagination of "if he was alive what would he think about this" and a great commercial name (why not)!
so i'm using his posters and things that he developed over time to get some shapes out of it, below a great example.
regarding the spacing, it is probably too loose for your intended display use
regarding the capital thickness, I agree with you, I think there is too much of a difference especially at a lighter weight. don’t worry about percentages too much, trust your eye
some issues that stand out are the bottom of the /s, which makes it look like the letter is leaning, the bottom of the /t, which currently extends a bit much below the baseline, and the lower leg of /k which feels a bit too flared/might be at too much of an angle
meanwhile you can check his "autobiography"

There's also this one, but i never read it, so i can't tell you what is about or even if it's worth buying

Unfortunately everything is in portuguese but the books you can try to translate and the documentary you can try to guess a little bit, english and portuguese have a different sequencing order of how to form sentences but giving certain context english ears can get context of what's being said
Translation in order:
