I've tried looking. And I've tried not looking, so I've given up. Water Worlds are a dime a dozen and always hurt when I realise they're not my first Earth like.
Yep, that stings. I still look at them on the system map and think "Yay! It's an EL."... only to be let down when I scan it and it turns out to be a WW with a little bit of brown as well as the blue and the clouds. Your first EL will be quite a kick, don't forget to use the selfie cam.
I've spent months out there, I was a pathfinder, but should be Elite by the time this latest mission is done. And I've never found an Earthlike. And that's fantastic, makes that first one all the more special.
That's quite incredible (and unlucky) odds.
I'm 18 EL in 3600 systems (I think around 500 of those system were from inhabited space before I set off on my, currently, 6 week trip) - so odds of 1 in 200 for me.
I found my first a couple days into the trip, and the second was the next system I jumped to. I've found several EL clustered in nearby systems. I've spent a chunk of the trip targeting mainly F class stars, but it seems that if the RNG wants you to discover an EL then it will throw one into some really unusual places. I want to find multiple EL in one system, so far I have an EL+2WW, and 3WW (2 of them TC), but no double EL in a system.
