I am missing some context here what was wrong with the original description?

It looks like that never occurs for Helvetica (A316600) due to the absence of kerning. However, with Arial (A316599) the description notes:

> a(29368) = 111111 is a first notable anomaly, because its bounding box width of 2675 lies between those of a(29367) = 49115, with bounding box width 2655, and a(29369) = 70002, with bounding box width 2681.

According to the wiki [0], "This is a less interesting sequence and is less likely to be the one you were looking for."

Confusingly, "more" means "please add more terms"...
