Include date of when longest tourism streak ended

Would be great to have the longest tourism streak to include the date of when the streak ended?

Longest tourism streak 6 parkruns (ended 14 August 2020 at Alice Holt)

I suggest that when a new streak equals that of the previous streak, it supersedes it; as it would be more useful to know if your latest streak is the longest. Also, if your current streak is the longest then it hasn't technically ended. Perhaps 'to' should replace 'ended'?

I'd agree other than the last point. It's a streak nonetheless. If I'd just bettered my previous one, it'd count in my book.

Rather than 'ended' perhaps 'achieved' which would work in both scenarios and keep logic simple.
