May as well forget scanning in

so basically you have no idea what the current capacity is so you're guessing...

If I wasn't right wouldn't they say so?  So that isn't guessing if that is the information available.

the 200 is year and a half old information, not exactly guaranteed to be factual now, especially since we know from the news they have added many hundreds of staff to the contact tracing crew. 

Your guessing at the current contract tracing capacity, especially assuming that contact tracing fails at 400, or any number for that matter - without any accurate data to support it...  This would probably be an example of cherry picking the evidence to suit your argument...
