With 3 strands the weakest point is the single strand side at the main cable but (as I now have had pointed out) the pull is 1/2 of the total pull or about 2/3 of breaking strain. In cables with more strands such as 4/5 the strength is closer to 100% as the split is closer to 1:1 each side. In this I have assumed a long splice so friction is high and the splice does not slip.
I also agree with Sandman that very few cables are used anywhere near their breaking strain therefore few will break even if the splice is less than 100%.

OK, so unless I am reading these wrong so far, this method has never failed anyone ..... Right?
Cityfarma- I cannot argue with your logic other than to say the raw straight cable ALWAYS failed before the eye.
Again, it is very stupid to say "it will never happen" but so far, no one has ever witnessed one fail.
One of the other pieces of equipment we ran was a $200K "fish tape" with a 20,000 pull capacity. We would argue with the engineers who built it all the time about one thing or another. While we wrong on many occasions with our assumptions because of something we did not take into account, we ended up stumping the pros more often than not because while they built it and tested it a couple of times, we used it almost more than 2000 hours per year (we were OT sluts) and we knew how it performed in reality vs. how it was designed to perform.
Again, I welcome all input and to be safe is to stay alive, but I am waiting to hear from someone that this failed them.
