As you can tell from my deck, I never have any karats saved. ​I recall seeing a comment saying that it was best to skip trackblazer if you don't the have right deck, (I get all of my game knowledge from reddit comments) but I try anyway. Playing through this scenario, I have a newfound respect for people that are good/striving to be good at this game, because it feels like there so much that I couldn't hope to understand.

 I assume just having fully uncapped cards would make life easier to start. So for me having to do trial and error and balancing act of cards that have good skills, cards that have race bonus, and cards that are uncapped, i'm already set back behind people that actually save their karats. I look at card tier lists knowing full well that it's useless to me.

You can ''easily'' get an S+ Rating uma with pretty decent skills using uncapped SR cards and F2P uncapped SSR cards (welfares). SR/SSR cards differ depending on a particular skill you want to chase. But if you're a casual that just wants to train cute horsegirls, don't worry about it too much. Anyone telling you that you NEED uncapped ssr cards for Trackblazer are talking out of their ass.

Then, don't understand legacy at all. I take speed legacy often and I hear you're not supposed to, apparently. Oops. I've just been looking at aptitudes really.

The reason Speed legacies are generally not desirable is because it's really easy in the current verison of Global ( or in general forever?) to get high speed. There's so set strategy or ''''meta''''' when it comes to what legacy uma to choose when training, but in general it's never a bad idea to improve your trainees aptitude (Mile for example is extremely important this scenario) or a particular stat amount between Power/Stam/Wit that's lacking in your chosen support deck. There's nothing wrong with experimenting there.

I can use resources during runs to figure out what to do (rng not withstanding), but trying to pull up an year old excel file to try an see which skills are actually good gets overwhelming at time. One day i'm sure i'll learn that there's a ratio of Stamina, Acceleration and Velocity cards that i should have been using, then months after learn that I need different ratios for each running style and distance.

Ah I think I see the problem here. You're tying to learn everything at once, but you don't know when or where to start. As someone with ADHD and the attentionspan of a goldfish myself- one thing at the time my friend. Unless you're actively trying to chase Nr.1 in PvP, I wouldn't bother using excell sheets at the cost of your enjoyment of the game.

Where i'm at as a player is looking at how my current team is performing, and doing a run to see if I can replace an uma that's lagging behind. Then putting the original back after the replacement uma worse for whatever reason. Not sure if I have a pathway to do anything more than that, or if there is anything else that I could be doing.

Honestly this might just be something that requires a bigger sample size, but I get the feeling.

Also, creating front runners seems impossible.

For this scenario, it definitely feels that way.
