Not sure what you mean, but probably the PoS result is not the same because the reward is variable according to the difficulty. You can check the graph on the first page of this thread to know what reward you can expect.
Basically, the best reward is when PoS difficulty is close to 0.00006 (which is the case right now).
You can track the difficulty on the fantastic Presstab's site here: http://www.presstab.pw/phpexplorer/TEK/index.php
Or you can also get the information by typing getinfo on the console of your TEK wallet.
