Dividend Payout Ratio

hello team,  attached is a table that I did for dividend payout ratio for guocoland.  I do not know what i can make up from this table.  It does not seem to be always in a certain range like 30-50% or 20-50% kind. It kind of go up high and then down low.  Should stocks with this kind of trend be avoided? Or what I can make up for this kind of stocks?  thank you again.
