The biggest difference is a drop of 111 points for reigning champion Marc Marquez, who had won all nine races this time last year but has only taken two wins - and suffered three DNFs - in 2015.
The next biggest points loss if for Repsol Honda team-mate Dani Pedrosa, no surprise given he has missed three rounds due to arm pump surgery.
The biggest increase is by Movistar Yamaha's Jorge Lorenzo, who has gained 69 points, followed by a 56 point rise for new factory Ducati rider Andrea Iannone.
Iannone's Pramac replacement Danilo Petrucci has also benefited massively from his change of team. The Italian has scored 47 points more than this time last year (Petrucci was injured early in 2014), risen ten places in the championship and has almost doubled his previous best tally for an entire season.
Other notable gains have come from Tech 3 Yamaha's top satellite rider Bradley Smith (+39 points and five positions), plus world championship leader Valentino Rossi and new LCR Honda rider Cal Crutchlow - both 38 points better off than at the halfway stage last year.
Further down the order, former satellite Honda riders Alvaro Bautista (Aprilia) and Stefan Bradl (Forward Yamaha) have unsurprisingly taken a step back, with Scott Redding's change from an Open to Factory class Honda yet to translate into better results.
Aspar's Nicky Hayden has remained on the same team and machine, but also lost significant ground, while Open class leader Hector Barbera is seven places higher on the Ducati compared to the Kawasaki-powered machine run by Avintia until Aragon last year.
