Certainly not intended!
If you read further into my post you will see that I am saying that there are certainly some Master locks that are nowhere near as easy as one would assume judging by the 'pick resistance' (or lack thereof) in the Master #3 style locks.
The lock you have pictured is indeed a lock that is very easy to pick(and one that is recommended to those new to picking to start with), although I certainly remember the first time I tried to pick one, years ago, and being frustrated by it many times.
If you have a particularly nasty bitting, then the lock you have might be more challenging than would be expected - if you can post a picture of the key that could help.
It is worth noting that due to the cylinder in this lock being far smaller than its cavity in the lock housing, it is easy to 'bind' the tension wrench against the housing - meaning you will know when you have picked the lock if your tension wrench is jammed.
If you can, get a deadbolt cylinder, and start with digital_blue's picking exercise, and you will find you'll be able to rake and spp this Master lock in no time.
Don't be discouraged! You have already picked this lock, and you can continue to learn from it, until it does become easy for you.
