Maverick is currently sitting 3rd in the championship, 24 points behind Martin. Had Maverick not suffered a gearbox issue, he would be just 4 points out of the lead.
Time will reveal what is happening for Maverick right now. Oliveira says his newfound form is related to better settings, which suggests Mav's elevated form should continue throughout the season. I often look to the tires when a rider finds a sudden improvement, but maybe Mav will surprise people this year.
He's had pace throughout his tenure with Aprilia, but he's struggled with his starts and with tire performance over race distance. Perhaps new settings really have unlocked the potential of the Aprilia.
