so are you comparing your hardware setups, software or (totally different) coins?
or all together?
all i see (from your screenshot):
you've recently made 0.00941 PTS in 6 hours
before that you've made 0.00965 PTS in 21 hours
i would call that an improvement

/edit: ok, i see there are quite huge gaps in your stats so i guess you're not mining 24hours a day
what is your miner configuration for these two hardware setups???
