Real world text editing traces for benchmarking CRDT and Rope data structures

Hey! Author of diamond types and the (linked) editing traces repository here. Would it be possible to make & share an editing trace or two from your application? Even a single user editing trace would be super helpful - like a big list of which objects were replaced by what values, in order.
I really want json based CRDTs to be fast, but one of the problems we have optimising this stuff is that there aren’t a lot of real world data traces around to use as baselines for benchmarking. I don’t know which parts of automerge are slow, and without that knowledge I can’t make them fast. If we have some data from your application, most upcoming json based CRDTs will almost certainly work well for your use case.
If you’re up for it, flick me an email or just open a PR on https://github.com/josephg/editing-traces
