Tryfan remeasurement confounds the doomsayers !

One of Wales' "elite" peaks has grown in stature after an official measurement to verify its height.
It was feared Tryfan, in Snowdonia, could have fallen short of the 3,000ft (914m) elite mountain status needed to keep as one of Wales' 14 highest peaks.
But enthusiasts who scaled it with GPS equipment found the peak came in at 3,010 ft (917.44m) - 8 ft (2.43m) taller than its official measurement.
The project's result was verified by a member of the Ordnance Survey (OS).
Tryfan, one of the best known mountains, in the Ogwen Valley, appears on the map at 3,002ft or 915m.
The news measurement is set to return it to the OS official height before the 1980s.
Before climbing Tryfan, John Barnard, from Mold, Flintshire, one of those involved in the re-measuring, said: "[We're using] exactly the same process as the GPS systems on your car, your sat navs, talking to the satellites, getting signals and measuring distances and then via some complex mathematics we can work out the height above sea level."
Down in the valley,critics wondered why it's Ordinance Survey pre 1980 height-which has been confirmed as accurate-was ever scaled down in the first place ?
