Not bad. You should get around 0.25 XMG per day when staked correctly

Spexx could you elaborate on this ? For me staking just means having the symbol green on my client

That is certainly an indicator, but to stake efficiently you need to send all your coins to yourself roughly every month, otherwise they become "stale" and will carry very little weight.
After you have sent all your coins to yourself, over the next two weeks you will observe the stake weight rising to a maximum which is around twice the number of coins in the wallet, then it will decline again over the following two weeks. The frequency with which POS rewards are received increases over the initial two weeks, then declines over the following two weeks.
If the wallet contains a lot of coins, it may not be possible to send all the coins to itself in one transaction. This simply means that the coins have to be split into multiple transactions. Allow a time delay of several minutes between multiple transactions to avoid a build-up in transaction fees.
I found in practice that it can be more convenient to run two (or more) wallets and send coins from one to the other, rather than sending coins to itself which might involve using the advanced coin control features provided in the wallet. Keeping it simple avoids confusion.
