You have to have those funds in separate wallets, otherwise your overall staking weight is 8800 MOIN and this will make results inaccurate. In other words it will make results of each separate address look bigger than it would be in reality.
According to KingCaper:
The staking weight shown in the wallet is only for informational purposes. The amount of coins in the tx.outs of one address only affects the difficulty (and likelihood of staking) for that address.
So if you had 2 addresses in the wallet - one with 10 MOIN, one with 500,000 MOIN - the likelihood of the one with 10 MOIN earning stakes is unaffected by the huge balance at the other address.
so the experiment should still be valid. thanks anyway for your input.
