Based on last year's Junior qualifying times, the 3rd placed man got around at about 118mph/19min. That gives a qualification speed of about 103mph/22min. That would effectively disqualify 10 or 15 riders at the bottom of the field.
Bearing in mind the collision involving Oliver Linsdell occurred as a consequence of two classes of riders/machinery simultaneously sharing the circuit, it's probably fair to say the club have already addressed the issue by making the Newcomers Race a completely separate event.
The bad crash in last years Junior wouldn't be resolved by this measure as both riders involved were well inside this new criterion.
We need to be careful not to alienate or deter riders from entering. Worse still, we really need to avoid a situation where a rider around the margins of qualifying isn't encouraged to take risks in order to get on the grid.
