Standar vs bullet vs blitz rating

So, i have like 1200(70% percentile) in blitz but like 800 in bullet(terrible in fast mode) and i think i can have like 1500 or maybe more in standar....

I use to play in blitz most of the time 5 minutes, maybe i am a bit better in 10 minutes. I start to learn very old 34. And for 3 years i have been studing something(when i have time), looking at openings, videos in youtube, and trying to learn general rules, integrate concepts etc...some tactics

So what does this mean, what is my real rating?. Is this very bad? Why is everything so easy in standar and so hard in blitz

Thanks

I really don't know.

In Standard you have time to figure it out, in blitz you dont.

It all depends on the player. I know a 2200 bullet player who sucks at standard time controls.
