I have a question about the payout specs.  I just have a small antminer aimed there which barely got under the
payout threshold last block.  I noticed my payout was a bit more than the DGM that I had earned, and was wondering
why.  Is that because of the shares paying out some TX amount?

With the greater hash at the pool, my DGM almost gets eaten and I have to keep putting an antminer back at the pool.
If the DGM was all gone, would I still get paid out in shares/TX fees?
