@badboy
I am testing this out in the web project and had a question about the persistence of data. If I call accumulate, refresh the page, call accumulate again, then submit the ping I get two values in my histogram. Is this expected? Or once the user refreshes their page should the old data be cleared?

I know we chatted a bit about how this should work with timing distributions, so wanted to get your thoughts.

2 values is correct (if this is a ping lifetime).
accumulate here is the recording function, so we persist that.

(for timing distributions stop is the recording function. Only calling start, but never stop means we're not recording anything, that's why we "loose" data there. that's no issue for memory distributions, because we only have a single function to call)

This looks great overall. There's a few minor things to fix, but it's very close to be merge-able.
