For average projects, I think it's a good idea to include 200 millihertz updates in the source code.
By default, debs can choose 5 Hz, 1Hz and 100 mHz. I think average amateur tracing projects would fit best at 200 mHz than at 1Hz or 100mHz.

They were assuming numeric values between commas, but you just get a
string of commas when there’s no fix. This was causing the RMC ate to
be parsed incorrectly.
