1:31.707 for Bagnaia with his latest lap to go P4; he follows that up with a 31.294 to go fastest.
With Quartararo and Miller testing the V4 Yamaha today, they will be building on what Augusto Fernandez did during the race weekend.
This is how the bike stacked up against the current package:

Pedro Acosta now fastest with a 1:31.487, and already back in the pits.
San Marino Grand Prix winner Marc Marquez is on the board with a 1m31.615s to go fastest after six laps on his factory Ducati.
Bagnaia has joined the action for what is an important day for him.
Luca Marini has taken over at the head of the field on the Honda with a 1m31.942s.
After the first hour of running, Pedro Acosta leads with a 1m32.050s.
Nine riders have set times. The most significant news of hour one, however, is the public debut of the Yamaha V4 for Quartararo and Miller.
Quartararo's reference lap on the inline 4 this morning was a 1m33s. His first on the V4 is a 1m36s.
Quartararo and Miller are now out on the V4 for the first time today!
Pedro Acosta leads the way with a 1m33.057s.
Fabio Quartararo has been out for a few laps, but looks like he was on the inline 4 to build a reference.
Plan from Yamaha suggests he'll spend most of today on the new V4.
Brad Binder on the sister factory team KTM has also taken to the circuit.
We have bikes on track!
Pedro Acosta on the KTM and Jack Miller on the Pramac Yamaha are first out.
Miller is on the current Yamaha spec but is set to jump on the V4 soon.
Half an hour of the test in the books and still we've had no one venture out yet.
Test runs until 6pm local time, so there's not exactly a shortage of opportunities to get laps in!
While we wait for bikes to hit the track this morning at Misano, check out our latest post-race column below:
Marc Marquez's classiest 2025 MotoGP win the ultimate retort to Rossi-loving haters
Across the grid we will likely seem new items being developed with a view to 2026, though perhaps not as much as we've traditionally seen in the past at this test.
This is also a good opportunity for Jorge Martin to work on his adaptation to the Aprilia.
The reigning world champion is getting stronger, but time attack remains a big weakness of his and today provides a perfect chance to work on this.
Ducati has a lot of work in front of it today, too. Pecco Bagnaia's tough Misano weekend has seen tensions flare again and patience is running thin on both sides.
Today is a pivotal day in getting Bagnaia out of the hole he is in for the final rounds of 2025.
The biggest story coming into today will be the public test debut of Yamaha's factory riders trying the V4.
Test rider Augusto Fernandez raced the bike for the first time at the San Marino Grand Prix.
The regular 2025 grid is taking part in today's test, as well as test riders Dani Pedrosa (KTM), Michele Pirro (Ducati) and Takaaki Nakagami (Honda)
Conditions are much cooler to how they were the last time we saw these bikes on track on Sunday afternoon.
So, unsurprisingly, nobody is rushing out of pitlane first thing.
Good morning and welcome to text coverage for today's post-race MotoGP test at Misano.
Pitlane has just opened on a fresh morning at the Italian venue.
