2 Hypothesis Certain amount of effort is needed to move to a higher range of Elo than a lower range Hour Rule by Malcolm Gladwell – dedicated practice needed to truly master any skill A players effort can be measured as a product of the change in Elo and time taken to move to the higher elo rating Effort = ( πΆπ‘’π‘Ÿπ‘Ÿπ‘’π‘›π‘‘ πΈπ‘™π‘œ βˆ’π‘ƒπ‘Ÿπ‘’π‘£π‘–π‘œπ‘’π‘  πΈπ‘™π‘œ π‘ƒπ‘Ÿπ‘’π‘£π‘–π‘œπ‘’π‘  πΈπ‘™π‘œ ) βˆ—(π·π‘Žπ‘‘π‘’ π‘œπ‘“ π‘π‘’π‘Ÿπ‘Ÿπ‘’π‘›π‘‘ πΈπ‘™π‘œ βˆ’π·π‘Žπ‘‘π‘’ π‘œπ‘“ π‘ƒπ‘Ÿπ‘’π‘£π‘–π‘œπ‘’π‘  πΈπ‘™π‘œ)

3 Methodology Collected Elo rating from year from Gathered all the elo rating of a player over the period of time Sorted the data based on the time period Effort calculated with the change in elo and the time taken to reach that elo Plotted a chart showing the change in Elo and effort wrt time

4 Results Effort of Vachier-Lagrave, Maxime

6 Effort of Caruana, Fabiano

7 Effort of Mamedyarov, Shakhriyar

8 Effort of Ding, Liren

9 Conclusion Collect data over a fixed interval of time
