Seems that the Greeks are sticking to their interpretation of the radar data (90° left, 360° right).
"We will start sending the main data from tomorrow, including the radar tracking and the conversation with controllers," one source who requested anonymity told Reuters.

The source close to the probe, and a second defense ministry official, said Greece stuck by its account that the plane had lurched violently in mid-air before it disappeared from radar screens. There has already been an exchange of information with Egypt, the sources said.
Egyptian authorities said they did not see the plane swerve and lose altitude before it vanished from their radars.
Greek Defense Minister Panos Kammenos last week said the aircraft took a sudden 90 degree turn, before flipping 360 degrees in the opposite direction and plunging from a cruising altitude of 37,000 feet to 15,000 feet, then vanishing.
"The picture we have off our radars is what the minister announced... we insist on that," the defense official said."
