Charles Leclerc was let down badly in Monaco Grand Prix qualifying. Ferrari's trust in its data, established in a flawed manner, caused it to ignore developments occuring before its very eyes. Only when it was too late to prevent Leclerc's elimination did the consequences of the blunder become apparent. The inquest began shortly afterwards.
Leclerc will be fortunate to make it back into the top six unscathed when he lines up 15th after being knocked out in the first part of qualifying.
He shoulders a minor proportion of the responsibility. Had he not locked up at Rascasse on the sole set of tyres Ferrari wanted him to use in Q1, he would have been a few more tenths to the good and not reliant on the team's flawed calculation of the cut-off time to make Q2, which it adhered to in a manner bordering on blind faith.
