Research Points are rewards that are gradually accumulated over time in Fortnite Save the World. A certain number of Research Points are granted per hour, though the rate and maximum storage capacity can be increased through Skills. It is used to progress through the Research Trees. The more Research Trees that are unlocked, the more Research Points the Skills are worth.
To achieve the maximum power level it is best to level your FORT stats equally, but ensuring you always level each skill per 10. This way you can utilize the bonus FORT stats.
