2: Long Buzzer Sound  when speed grows (acceleration indicator for high speeds)
3: combined Long Buz/Short buz sound, when 1 and 2 are true

B. During Speed Genie result display
1: Festive sound pattern if the Personal Best average speed was achieved.
2: 3 digits of the N-second max average speed result encoded in the sound as follows (code similar to Roman numerals, except for 4 and 8)

1 = 		.
2 = 		..
3 = 		...
4 = 		....
5 = 		_
6 = 		_.

8 = 		.._
9 = 		._
0 = 		__

where

 . = ~100ms short sound
 _ = ~300ms long sound
 __= ~600msec  for zero (not truncated)
 silence separator between digits: ~300msec silence

The numeric speed result is repeated 3 times and then every 2 minutes when Speed Genie results are displayed on the screen
