I have only been keying for a couple of months, and I have a 'Very Good' rating. How do I find out what I'm doing incorrectly?

I just finished a New Zealand directory page, and nearly every entry on the page was an abbreviated name, i.e. 'Jas', 'Nckls', etc. I interpreted the name into 'James', 'Nicholas', etc. as best I could. There were over 750 entries on this one page.

Also, NONE of the section names were being recognized as 'legitimate' entries, i.e. 'Hawera', 'Wikiwiki' etc., but if I used the region name instead, like 'Auckland' 'Hawke's Bay' etc. there were many sections with each region name. There were sixteen sections in all, and I ended up using both, even though I had to click the button that this was 'correct' each time.

I am concerned now that my accuracy rating will suffer for these entries. Any suggestions?
