I had a interview like that but it was closer to the beginning my claim so it must have been a different thing.

I'd just go with you did your best and worrying won't change anything.

closing and a settlement can be two different things.

I had a 1999 RSI case that closed in 2000 as i was mostly Ok and stable.
When it all began back up again in 2003 and with new /other sx I wasn't sure if it was a new injury or a re injury - so that complicated my "new" wc claim and confused my new dr on my care/treatment plan.

Settlement final monies-
Just make sure to ask for more than you need for the future because they will counter offer/negotiate down.

Don't feel pressure to sign anything if it doesn't feel acceptable.
Because when you sign it's is pretty much done. You might have a limited time to reconsider. Before you are sent a second set of papers to confirm the agreement.

But don't hold me to that - I'm just trying to recall how it went for me in 05 and in Oregon, other places might be different.
