I've got 5.06V out of the dock connector which I'm using to power the pi. My question was more towards the voltage across TP1 and TP2 on the pi itself since I'm getting sticky keys (especially while trying to login) once I've booted up. I've read this is sometimes due to low voltage and was wondering if splicing my own cable (making it shorter and with less adapter connections) will help.

Right now I'm getting 4.74 from the lapdock battery. I used a couple extra adapters in my setup rather then splicing cables.
You not backwards powering the PI from the USB peripheral ports are you?
Earlier on it was stated that a custom USB 'Y' cable that took the output of the LapDock micro USB port and sent the power wires to the micro USB and the data lines to the full size USB.
I'm not. I have one of these and have cut the 5v on a short extension cable coming out of the port with data. The power-only side goes to a micro usb adapter and then into the pi.
