Calligraphic Brush, Blob Brush appearance anomalies at small brush sizes (1 pt and above)

Illustrator 22.1, though this is extant in all versions I'm familiar with (since at least CS5).

When drawing with a calligraphic brush (and thus also with the blob brush) at small sizes, certain tight curves result in anomalous shapes extending out from the expected area covered by the brush. The screenshot attached is around 15mm across. AI file also attached. Expected result is that the brushed area corresponds to the shape of the calligraphic brush along the whole length of the path.

This is obviously not fixed, so the previous status is removed.

We need to make some design changes to incorporate real thin brushes rendering at high zoom. Please use the comment section to indicate your workflows so that we can prioritize this.

This is a major problem. Adobe has been neglent in resolving this and other big issues. It seems they think that they are the only ball game in town.
Occasionally Adobe asks how they can improve thier product. I share. Their response, regarding their ****** "Help" tool is to send you to Youtube. Seriously?!
This "Blob Brush" issue has been one that should have been solved a few years ago.
As they say in the NFL, "Come on man!"

PLEASE! This is a major problem with practically every piece that I produce and really slows down my workflow having to go back and fix it.

This is also occurring with the blob brush, and at larger sizes.

I am having the exact same issue. When I paint a tightly curved line or sometimes loose curved lines the line stroke does not continue and is disproportional to the line width I painted.

Drawing with touch calligraphic brush, most obvious at 1 pt size, there will be funny filled in blobs along the path. Playing with the points and curves doesn't get rid of it. If the object is resized by 200% or so the "blobs" will go away, but this is not a good fix if the lines need to stay editable.

Has been reproduced using CC 2017 on an HP Spectre 360 with a stylus, AND a Mac (OS 10.12.6 Sierra & CS5) with a Wacom.
