Yes, they are challenging! What makes them more challenging is having a question and not getting a response. I have 'paused' in keying these because of that. However, as it appears that the keying of these records is going slowly, I will start again after I'm done with what is in my current project list.
I do refer to the wiki info but that is unhelpful as it only applies to records that are 'perfect.' It would be helpful if the wiki pages also showed the keying portion (not just colored lines pointing to one or two records within the document).
