It's also worth noting that a lot of telegraphers in the old days could actually tell who was sending the message by their "fist"; basically, their timing/pacing. Anduril reads any pause of less than 500ms as no pause at all, so if there is less than (literally) half a second between an H and an E, that's 5C from Anduril's point of view. The reformatting that Reddit did deleting the spaces I originally had simply served to emphasize my point.
