Thought my maths was better than this, explaining interest %age

EDIT: Thanks for feedback, appreciated :]

Hi,

fairly new to this so feel free to shoot me down in flames if need be :)

Trying to work out the percentage interest and my account summary says...

Account value: 3,584

Return since account opened: 311

Personal rate of return: 17.43%

I can't make the sums work

I've have initially invested 3,273.

Have tried doing all combinations of mathematical acrobatics I can think of and can't get the figures to end up with 17%...

Can anyone explain how to calculate this properly?

I have FR255 and decided to get back into running after a year or two of not running.

There used to be 3 coaches Amy, Jeff (and I can't remember the third one) - now there is just 'Garmin Coach'

have the different coaching methods been binned?
