Summary of Issue: in practice, difference between \"blink\" and \"flash\" still unclear, even with appendix
Comment (Including rationale for any proposed change):
It\'s unclear here what the difference between blink and flash actually is, in practice. Looking at the appendix, there\'s a definition for \"blink\", but strangely not for \"flash\". The note in the appendix definition of \"blink\" still leaves me wondering:



\"The slower blink is in contrast with flashing, which refers to rapid changes in brightness...\"



If blinking is a complete on/off, is it not simply a special case of flashing?

Proposed Change:
Just stick with flashing or blinking throughout the document, as it\'s confusing (and in practice, completely irrelevant I\'d argue) to distinguish between a blink and a flash.
