I plan to spend a Day on each key to ensure i really do learn this stuff
A whole day, WOW! I wish I could internalize new concepts that fast.
Seriously though, if you spent one day on a scale and then move on, you're not going to really learn anything. Or at least not to the point to where you can use them effectively in improvisation. Studies show that it takes a minimum of 3 weeks for the brain to fully assimilate new concepts. You may be able to learn a new scale a day, but you're not going to internalize it.
If somebody asked me to spell an Altered (diminished-whole tone) scale in any given key, I could do it no problem. But if I was improvising, I would probably struggle to instantly recall that scale for certain chords (keys) simply because I haven't spent the necessary time in order to play that scale without thinking about what notes are in it.
Start with the major scale and get that REALLY comfortable in all 12 keys. Comfortable to the point where you don't have to think about the notes. Only when you have that down, move on to the modes of the major scale. The most common are Dorian, Mixolydian, and Aeolian (natural minor). If you got your majors down, it makes learning the modes a lot easier.
Once you got those move to the melodic and harmonic minor scales and once those are mastered, move on to the modes of those scales.
Then add the diminished and whole tone scales.
You should be able to play all scales in broken 3rds, 4ths, triads, and 7th chords. Add to that different digital paterns(1235, 2346, etc.) Until you can do that, you haven't truly internalized the scale. Rarely in improvisation is a scale played straight in a scalar fashion for more than a few beats.
Oh, and do them all full range of the horn. EX: C up to High F down to Low B and back up to C.
Don't saturate yourself too quickly. If you do, all you'll do is skim the surface and you won't REALLY learn what you're trying to. Take small steps. Get a solid foundation and build on that. It's better to know one scale thoroughly than to learn 20 half assed.
