Scudo,
One problem with raking is that you don't get the same feedback as when you SPP.
The problem you are experiencing may be security pins. I find these much easier to deal with by SPP (single pin picking). If you lift a pin and it moves freely with only spring pressure from the pin spring when the plug is under tension, then it is not set, and is not binding. If it moves completely, and you feel no pressure from the spring, then either the pin is correctly set, or the driver pin is a security pin and is not set correctly.
When you are at the stage you described, with 'four pins set, and the final pin not binding', you are likely dealing with security pins. Try using a hook or half diamond pick and try applying a little lifting pressure to each of your 'set' pins. Pay careful attention to your tension wrench. If your tension wrench tries to turn itself backwards when you lift a pin (counter-rotation), then you are dealing with a security pin (spool, etcetera) in that pin stack. Lift that pin further until it sets again. It may cause other pins to drop first. That is ok, just reset them again once the pin stack you are lifting is set. Keep doing that with each pin stack until the lock opens.
Only keep lifting pins that give you counter rotation. If you lift, and the pin does not want to move up any more without significant pressure, do not keep lifting it, it is probably already properly set. Just about any pin will give some tiny amount of counter rotation if you are forcing it so hard that it is being forced over the sheer line in spite of it being properly set.
So to summarize, try lifting the pins again. If you get counter rotation, ease the tension a bit and continue to set the pin. If you get no counter rotation on that pin, move to another pin stack. If no pins are binding or set, use more tension. If some are set, and the rest are not setting, either you are dealing with with security pins, or a pin is over set.
