I easily get 100% success transmission to a diamond chest with an advanced insertion pipe, and this is pumping both 1280 items (20 stacks) per second via energy link and diamond chest, and 20 per second via condenser. I'm afraid something's with your setup that causes it, and unless you can reproduce it in simple conditions without fail, I can only say that you're drawing conclusions without a sufficiently sized data sample.

Good job on fixing it, but on a tangent, why are you mainly using buildcraft in your factory? It is heavily agreed that pneumatic tubes are far superior to buildcraft pipes, as the level of accuracy, speed and overflow control over buildcraft is staggering. There are few instances where wooden pipes outperform filters, and basically the only main one is outputting at an amazing rate from an auto crafting table via wooden pipe and energy link, and that level of speed is way faster than machines could hope to process without huge amounts of eu supply.

Mind if I take a look at your factory? There's almost no factory that needs to actually be large (even my solar factory at 2.5 solars a second production could fit in a 12x4x5 area, possibly 10x4x5 once I optimize it more), and I'm sure I can find many ways to improve its efficiency.
