I see thank you. So for example I ran 7.42 indoors in january and finished this season with 11.57 pb so this could indicate I needed more speed endurance in my training?

11.57 is worth more than 7.42, but at your level you are probably progressing too fast for your indoor results to have much predictive value for your outdoor season.
