I would gratefully thanked that this my first time to see such. We are also playing tipping competition here in PNG. Is this method sometimes come true?

Yes, the method I use “sometimes come true”. You can assess its performance by the success percentages of previous forecasts which are included with all predictions. You can also compare the forecasted points differences with the actual differences observed after games have been played.
