it is more, at least in my case. I am staking since 3 weeks and received 3 times as much as the stratispool told me I would get.
1% is way too low.
It's bit of a random process anyway...Maybe you got lucky?
I mean, I've been staking about week and a half now, and I've got nothing.
On the other hand, I'm not really expecting to be rewarded, since my wallet says 'Expected time to earn reward is 42 days' .
And frankly, I don't even care

Stratis is much bigger than getting a reward every now and then.
I believe in this concept, and I'm just happy to be part of it.
