We needed something a bit better. So not sure how useful this is to folks - but on the principle of share early and often; you can fi...

Am strongly suspecting that, when using the RMT system in loop rather than in one-shot mode; it either ignores, or gets confused by the sentinels; and mis-counts during the final ticks in the final block. If one ensures that all blocks are fully filled with no '0' length blocks (i.e. not use the 0,1...
