Shareholder wealth calculation

When we calculate the total shareholder return how do you know which method to use is best? and how many methods are there? ie the one below and ….dividend yield plus share price increase!!!

also if we use dividend + increase in share price/ share price at the start, if there is a decrease in the share price is this method still appropriate as we can mention that the company isn’t meeting there objective?

Hope that makes sense

Thanks
