A certain website has a counter which records the number of hits each day, and keeps a running total. The site gets between 10 and 20 hits, inclusive, per day.

The webmaster noticed that the running total was always prime.

What is the largest number of days the site could be up?
What is the largest number of days if the counter did not start from 1?

(In reply to re: some computer findings by Charlie)

I think a bottleneck occurs around successive primes
