Most people can scarcely count to ten as it is.

It might be OK for scientists and IT contractors, but the majority of people would be utterly confused and would make mistakes so frequently as to render such a system unworkable.

Most people can scarcely count to ten as it is. Are you looking forward to being stuck behind the elderly person with short sight who has to spend ten minutes squinting at the display trying to work out where the 4 has gone?
