Fixing confused bayesian matching data?

[Philip Matthews]

Just wondering if anyone has any advice on what to do with some very confused bayesian matching data?

Right now, when I import new transactions (either CSV or QFX), they mostly don't find a match anymore. Only around 20 - 30% match.   This is probably because I like to rejig my accounts from time to time as I continue to figure out what works best for me.  Looking through the ".gnucash" file, I see lots of slot entries with account names that don't exist any more.

For a while, I was just putting up with it and assigning transactions to accounts by hand, but now I am starting to get tired of this.

A couple of options have occurred to me:

1. Just delete everything between <act:slots> and </act:slots> for each account.  This is simple, if rather drastic. But do I do this again in a month when I make another small change to my account structure?

2. Write a Python program that goes through the .gnucash file and deletes slot entries that point at accounts that don't exist any more. 

Comments?  Other thoughts?
