little confused here... can't seem to pool mine

i started by generating a 200gb plot and setting up pocminer for solo, saw all the network messages (basetarget, height, generationsignature) and some shares being submitted

then i grabbed dcct-miner and pointed it to burst-pool.cryptoport.io and my plots directory, but the only output was "19mb read/209gb total/no deadline," and it climbed to "32mb read" over the next hour or so without saying anything else, so i killed it. i tried running it again, and it just shows "0mb read/0gb total/no deadline" now. what do the "mb total" and "mb read" bits indicate?

next, i set up burst-pool-miner the same way. it shows the familiar network messages, but has made no mention of shares after running for hours

my account is visible on the network, and i delegated the pool as my reward assignee. my plots directory indeed exists, is populated, and has 777 permissions on the directory and the plot file. neither miner throws any errors, but the pool website shows no indication that i'm mining

some help, please?
