usually when you have a check that is Highway Stat + Advanced Skill/Defences, each point of Advanced Skill or Defence will be worth [Multiplier] amount of points in Highway Stat

for example, on <a href="/wiki/Engage_in_a_bit_of_recruiting" title="Engage in a bit of recruiting">Engage in a bit of recruiting</a>, each point of <a href="/wiki/Dreaded" title="Dreaded"><img alt="" src="/w/images/thumb/f/f5/Sidebardreaded.png/20px-Sidebardreaded.png" decoding="async" width="20" height="26" srcset="/w/images/thumb/f/f5/Sidebardreaded.png/30px-Sidebardreaded.png 1.5x, /w/images/thumb/f/f5/Sidebardreaded.png/40px-Sidebardreaded.png 2x" /></a> <a href="/wiki/Dreaded" title="Dreaded">Dreaded</a> and <a href="/wiki/Zeefaring" title="Zeefaring"><img alt="" src="/w/images/thumb/8/80/Zeefaring_sidebar.png/20px-Zeefaring_sidebar.png" decoding="async" width="20" height="26" srcset="/w/images/thumb/8/80/Zeefaring_sidebar.png/30px-Zeefaring_sidebar.png 1.5x, /w/images/thumb/8/80/Zeefaring_sidebar.png/40px-Zeefaring_sidebar.png 2x" /></a> <a href="/wiki/Zeefaring" title="Zeefaring">Zeefaring</a> are worth 10 and 15 points of <a href="/wiki/Dangerous" title="Dangerous"><img alt="" src="/w/images/thumb/a/a4/Bear.png/20px-Bear.png" decoding="async" width="20" height="26" srcset="/w/images/thumb/a/a4/Bear.png/30px-Bear.png 1.5x, /w/images/thumb/a/a4/Bear.png/40px-Bear.png 2x" /></a> <a href="/wiki/Dangerous" title="Dangerous">Dangerous</a>, respectively. so you would set your multiplier for <a href="/wiki/Dreaded" title="Dreaded"><img alt="" src="/w/images/thumb/f/f5/Sidebardreaded.png/20px-Sidebardreaded.png" decoding="async" width="20" height="26" srcset="/w/images/thumb/f/f5/Sidebardreaded.png/30px-Sidebardreaded.png 1.5x, /w/images/thumb/f/f5/Sidebardreaded.png/40px-Sidebardreaded.png 2x" /></a> <a href="/wiki/Dreaded" title="Dreaded">Dreaded</a> to 10, and your multiplier for <a href="/wiki/Zeefaring" title="Zeefaring"><img alt="" src="/w/images/thumb/8/80/Zeefaring_sidebar.png/20px-Zeefaring_sidebar.png" decoding="async" width="20" height="26" srcset="/w/images/thumb/8/80/Zeefaring_sidebar.png/30px-Zeefaring_sidebar.png 1.5x, /w/images/thumb/8/80/Zeefaring_sidebar.png/40px-Zeefaring_sidebar.png 2x" /></a> <a href="/wiki/Zeefaring" title="Zeefaring">Zeefaring</a> to 15.

or I'm just missing what your question is and dumping info you're already aware of. sorry in advance
