Follow-on to tabulary + longtable + captioning

Question

I was able to use the coding provided by Justibus: Several caption problems in longtable and tabulary.

What my question is - now that i've been able to make my table wrap columns and break over multiple pages whilst maintaining tabulary. I now find that the first column (in my case of three colunns) is being compressed to far in it's appearance.

How can i set a minimum limit of compression to the columns?

My understanding of coding is beginning and so have been unable to find a clear explanation on in other posts of how to put a minimum column width limit with tabulary.

Any help with this would be appreciated and if the list in the final cell could be itemized it would be excellent.

MWE:

\documentclass{scrartcl}

\usepackage[hypcap=true]{caption}
    \captionsetup{labelfont=bf, justification=justified, singlelinecheck=false, format=plain}

\usepackage{tabulary, booktabs, longtable, ltcaption}
\usepackage[referable]{threeparttablex}

Answer 1

If you add some hyphenation points and restrict each column to .2\textwidth you get

If you use .25\textwidth it doesn't need to hyphenate in this case, so you can choose:-)

(The \caption usage still needs fixing)
