Ha ha wow you're taking this in every conceivable direction to avoid answering a yes/no question. OK, deep breath:
The Chief Medical Officer during one of the public briefings said we were following a similar curve, and we were about 4 weeks behind. He later revised that down to 3 weeks and someone from the government, not sure if it was him, later said it was 2.
The reason all the companies in the world who compile statistics don't start from the first case, the first ten cases, the first death etc is because the circumstances of those cases can vary wildly. Your first case could be a tourist who obeys quarantine and stays in their hotel, or an asymptomatic drinks vending machine worker who visits 5 nursing homes a day (extreme example given to explain the concept, not saying this is what happened).
Speaky pointy man help you understand.
