Ganking in open is rather urban legend. However, yes - its happening sometimes.
Its like a monster in dark place in childrens room. Its growing and its sooo scary. But if you turn on the light there is no any monster. You just need to play few times and you will see there is no monster, no darknes.
Firstly, in our crazy language, the plural of sheep is sheep..don't ask why, it just is! Also, singular of trousers is trousers! Hope this clears up everything for you!
Secondly, ganking is 'urban legend'? You are falling into the classic ED forum trap of 'it hasn't happened to me..ergo, it doesn't happen!'
Oh dear Kobayashi

..are you sitting comfortably? then I'll begin..
I have been griefed/ganked - or more accurately - killed due to insurmountable odds, many, many times..but it is not a problem..why?
..because each time I was in a system or at an event looking for trouble..just not quite as much as I found!
My record is 3 ganks from two different groups in about 10 mins, while trying to get to a RES for a bounty hunting CG. I informed cmdrs at the station of the unfortunate events befalling me by comms - some sympathy, some laughing..when I materialised back at the station for the
third time to say 'byeee everyone..this is ridiculous, I'm going solo', it is safe to say the responses were well, it was mostly 'lolling'!
I then used solo to travel to the RES & returned to open, where my day continued on it's inexorable spiral down the toilet, as I was subsequently killed by Sundae's FDL with the help of some NPC PP enemies - a FGS & FAS wing that chose a particularly inopportune moment to attack me. This was the moment I discarded the PP once & for all! All in all..an expensive, miserable 20+ mins in my ED career!!
There is a vid of this too..but the only way you'll see it is if my PC is stolen..like celeb sex tapes, but slightly more embarrassing!
Having said all that, sure the anecdotal evidence sounds bad in isolation to the unitiated; but firstly I never run & secondly, in normal, everyday game play I have been attacked by apex predator wings maybe 3-4 times since I bought the game 18 months ago..as others have said, well publicised events have the potential to get hairy..
..you rolls the dice & you takes your chances! Hmm, now where have I heard that before?
NB - OP? Not sure where your figures have come from - looks like you divided number of hours by the corresponding number of mins - best to use the same units with numerator & denominator yeah? otherwise you get into territory of dividing apples by oranges which never ends well in exams!
I've got some good news for you, however - your cmdr deaths have only taken up 12.5 mins of your game time & you divide this figure by 24000, which is way lower than 1.66%! So you're
even safer than you thought!
