In the end, it's always uncertain before you know what the outcome is. Stuff looks good on paper and it still doesn't show in the value at times. While sometimes shit you wouldn't ever think would make it goes sky high all of a sudden. Seems like you've put some thought in it, watch out for a confirmation bias and becoming overconfident though! Past results are no guarantee it will repeat. Especially since you mention it was a shocker to you and aren't sure why you got the results that you did..
