Do the calcs -protect the cable - is junction rated sufficiently- if all works out it will be safe and ok - have confidence in your quals, experience and knowledge - just because something is new/unusual doesn't make it wrong - conversley - why are rings so great! there is a big shift back to radials. Historically, Rings only came into being when it was decided that they were a safe way of extending existing radials as post war affluence increased the number of electrical items in homes. i.e. existing ccts were all radial , they were becoming overloaded. So it was easier and cheaper to extend the radial back to the CU than rip out existing and rewire in larger CSA cable. Rings then became the norm as copper was so cheap - how times change, time to re-invent the wheel so to speak - hence shift back to radials (Nearly all the contiinenet is on radials)
If in doubt - do a lick test - you will know if it is a lollipop:tongue in cheek
