In reply to Offwidth:
For the record from that other thread these were how the classics moved:
Since the 83 guide the following 2/3 star classics changed adjectivally (in four editions of the BMC guidebooks)
Goosey GG E4 to E5
Old Friends E3 to E4
Wolf Solent E3 to E4
Impossible Slab E2 to E3
Goliaths Groove VS to HVS
Not to Be Taken Away HVS 5c to V4 6b
Namenlos HVS to E1
Stanleyville E3 to E4
Balcony Buttress VD to S
Agony Crack VS to HVS
Left Twin Chimney M to D
Wuthering E1 to E2
RHRHBD S to HS
FBD HVS to E1
Kirkus Corner HVS to E1
Unprintable HVS to E1
Tippler Direct E2 to E3
Crack and Corner HVD to S
Which I make 18 out of 80 and in the graded lists most of those routes are low in the grade band so have shifted half a grade at most. Never mind the facts getting in the way of a good story though.
Just for the record the extra upgrades (on top of GGG, FBD, LTC and C&C) from '89 to the latest guide, in the 2 &3 star category, were:
Orang Utang E1 to E2
Crypt Trip E5 to E6
Weather Report E5 to E6
Silk E5 to E6
Indian Summer E5 to E6
Punishment E4 to E5
Curving Chimney D to VD
Wall of, Sound E5 to E6
Chameleon E3 to E4
The two down-grades were Green Streak to VS and Paradise Wall to HS.
All on 120 routes (in '89)
Simon Caldwell also made this point:
"Out of interest, here are the benchmark routes for Stanage from the 1963 guide, with their current grades from the 2007 guide.
Easy - High Neb Gully (Easy)
Mod - October Crack (Diff), Left Twin Chimney (Diff)
Diff - Broken Buttress (VD), Helfenstein's Struggle (VD), Physiology (VD)
HD (who said these 'half' grades were a modern invention?!?) - Overhanging Chimney (S 4a)
VD - Cave Buttress (S 4b), Wall End Crack (S 4b), Flying Buttress (VD)
HVD - Creepy (S 4a), Little John's Step (S 4b)
S - Marble Tower Wall (VS 4c), Paradise Wall (HS 4b), Robin Hood Zig Zag (S 4a)
HS - High Neb Girdle Traverse (not listed in 2007, HS 4b in 2002), Gargoyle Buttress (VS 4b)
VS - Right Hand Tower (HVS 5b), Milton's Meander (VS 4b), Inverted V (VS 4c)
HVS - The Blurter (HVS 5b), Right Unconquerable (HVS 5a), Kirkus Corner (E1 5b)
Extremely Severe - Quietus (E2 5c), Count's Buttress (E2 5c), The Tippler (E1 5b)
This fits in with my usual experience. After most crag visits, I look up the routes in my old guides to see what they say, and on average I'd say VD and below are a grade easier in the old guides (sometimes 2 grades in the oldest), VS is around the same, Severe/HS are all over the place."
