Hey,

> Currently each entity creation and subsequent claims are unique API calls. So using the wbeditentity will probably result in an improvement. Thanks for the suggestion.

I second that suggestion. It should definitely not take 2 weeks or more to add a mere 50k items. In case your bot is PHP or could easily do some PHP, then [0] and [1] are probably of use to you.
