I used to have a combination of long and short flashes, but due to my miscommunicating that to Mark, his User Guide ended up with the simpler pattern that I then implemented.  We can have another think.

The on time is currently 15ms (as short as I can efficiently do) and the off time 150ms, so there’s not a lot more to play with there.

I’ll have another think.
