I'm getting a lot of "Share above target" messages when I put cgminer in verbose mode. My hardward ghs as reported in cgminer is right, but in the pools it always gives me a lot less credit, like half. Here's a log:

Here are some ways I've tried invoking it:
rem causes "Share is above target" messages
rem cgminer -o stratum+tcp://mint.bitminter.com:3333 -u me.1 -p 1 --bflsc-overheat 90
rem also causes "Share is above target" messages
rem cgminer -o
http://mint.bitminter.com:8332 -u me.1 -p 1 --bflsc-overheat 90
rem also causes "Share is above target" messages
rem cgminer -o stratum+tcp://nl1.ghash.io:3334 -u me.worker1 -p 1 --bflsc-overheat 90
rem also causes "Share is above target" messages
rem cgminer -o
http://mint.bitminter.com:8332 -u me.1 -p 1 --bflsc-overheat 90 --fix-protocol
Any ideas on what this is about or how to fix it?
