Srqrebel, I believe you are correct. For anyone trying to stake with a smaller amount, I'd suggest making sure all your coins are in a single UTXO. For example if u buy 100 xspec, withdraw it to your wallet, and then buy and withdraw another 100 xspec, your wallet will consist of 2 unspent transactions (UTXO). In this case, send all the coins to yourself, now they are all in 1 UTXO. Statistically, it shouldn't make a difference in the long term, but having a higher staking weight seems to give rewards on a more consistent basis, instead of varying randomly. The amount you earn is the same, just less variability in when staking occurs. This is just my observation, I may be wrong.
