Yes. Everything is fine. Don't worry.
Mining is probabilistic in nature: if you find a block earlier than you statistically should on average you are lucky if it takes longer, you are unlucky. In a perfect world, you would find a block on 100% luck value. Less than 100% means pool was lucky. More than 100% means pool was unlucky.
We have seen 600%, 800%, or even 1500% luck. That could happen and nothing we could do.
We highly recommend you read this article What is Mining and Mining Luck? which describes what is luck in detail.
