EDIT: This system has evolved over the years. See the Primel Metrology Wiki for the most up-to-date description.

As of 1202/03/01[z]=2018/03/01[d] I use:

I don't think this is a problem when used as a radix point, only when used as a base marker akin to your former use of a subscript after the number. I've seen hideous examples of two consecutive semicolons, the one being a base marker and the other a punctuation semicolon, but the Humphrey point when used inside numbers as a separator between the integer and the fractional part doesn't suffer from this problem. Note also that the punctuation semicolon is followed by a space, while the semicolon as radix point isn't.
As for decimal numbers, I now want to avoid using a center dot ($$\cdot$$) as a combination decimal radix point/decimal marker, because it's just too useful as a multiplication operator.
I concur, though I'd actually prefer &#215; (U+00D7) as a multiplication symbol but for the fact that there are not one but two X-like symbols to clash with: not just the algebraic x (I remember switching to &#183; once I started pre-high school algebra) but also the X a lot of us, including me, use for ten out of necessity.
I don't want to use the period ( . ) as a decimal marker on integers, because it too easily registers as a full sentence stop rather than as a base marker.
Again, I think this isn't an actual problem. The punctuation full stop, like the semicolon and the comma (which latter the Continental Europeans use as a decimal 'point'), is followed by a space, while the radix separator isn't. It's a far cry from the use of punctuation marks in names, like 'Yahoo!', in the middle of a sentence which is really in conflict with punctuation usage.

Even my use of an asterisk for marking dozenal numbers, though it could be improved upon, doesn't conflict with the punctuation asterisk, because it comes before the number while the punctuation asterisk comes after the text. One good sign of a true clash between usages is that it's blatant, it sticks out, it becomes one of the pet peeves people talk about at the pub.

Edits to the original post:
• In the base units table, I added a Symbol column with proposed abbreviations for the units.
• I also added a note about how to get Greasemonkey and MathJax to render all these TeX insertions.
• Started the Time Units section (added table).

[color=red]CAVEAT: This post reflects an earlier point in the evolution of Primel, when I was using the SI gravity of 9.80665[sub]z[/sub] m/s[sup]2[/sup] rather than the gravity which achieves ′ell-length = 46.5[sub]d[/sub] inches. I was also using a prefix form of base annotation, whereas I prefer subscript annotations now. I was also abbreviating the power-prefixes with uppercase vs. lowercase (e.g. unqua = U, uncia = u) whereas I prefer using special symbols now (e.g. unqua = u↑ , uncia = u↓ ). And of course, I have deprecated the ′kernel in favor of the ′morsel. (No more barleycorns, except as a footnote!)

Nice to see the Primel system moving forward! I'm bit of a fan.
Numbers in my posts can be taken as dozenal, with the exception of italicized numbers which are decimal (unless otherwise specified).

Effective: 1E-08-11EX (23-08-2014)

Note: I've updated the summary table in the original post:
• Added links to the new detail posts on Primel Mass Units, Primel Force Units, Primel Energy Units, Primel Power Units.
• Added numerous other units and reorganized the table into sections on Mechanics, Heat/Thermodynamics, Electromagnetism, Chemistry. (I'll eventually add detail posts about these.)
• Settled on the basis for the electromagnetic units. Just as with TGM, everything hinges on the choice for Ampere's magnetic force constant kA. The size of the force chosen determines the size of the base unit of current, by definition. All the other units follow from that. But the choice is completely arbitrary. Historically, people have picked "round" numbers in their chosen base that yielded "convenient sized units". SI picked d[10-7] newton/amp2. Pendlebury picked z[0.6×10-9] Mag/Kur2. After some trial and error with a spreadsheet, I picked z[0.6×10-5] &#8242;forcel/&#8242;currentel2. This leads to a &#8242;capacitel of about 2 farads, and a &#8242;fluxdensitel of about 2 tesla. Deviating from this choice of kA in either direction shrinks one of these at the expense of blowing up the other to an unreasonable size.
• Settled on the temperature unit (&#8242;thermel) EDIT: (&#8242;temperatel). Pendlebury started with the "specithermacity" (specific thermal capacity) of water, determined a rough value for the Calg, saw that the biquaCalg was coincidentally close to a round decimal number of kelvins (d[0.1] K), and rounded the biquaCalg so that a whole number of them (d[1000] = z[6E4]) would cover the Celsius range. I followed the same program and discovered a similar coincidence with the &#8242;quadquathermel &#8242;quadquatemperatel, and rounded it to d[0.4] kelvins, so that exactly d[250] = z[18X] of them cover the Celsius range. This causes the Calsp and the &#8242;specithermacitel to be slightly below the actual range of values for the specithermacity of water, but so be it.
