Glad I just finished my cup of tea, otherwise my laptop would be wearing it whilst I burst into laughter at the previous comment.
Also the reason why RYR often request different levels to what is filed is that nearly all their Flight Plans are RPLs so it just spits out the same speed, level and route on a repetitive basis.
If you are bombing around in turboprops or in jets on very short sectors then RPLs will probably still bear a close resemblance to what gets flown in terms of level etc.
