Giggles numbers are way off.
How about 2 simple comparisons - based on how much B scales need to rise to get to A scales. One based on the pre-cut A scale (30/6/99) and one on current A scales.
Pre cut
FO1-4 - need 20-24%
SFO1-6 need 29%
CN1-2 need 31.7%
SCN1-17 need 34%
Post cut
FO1-4 - need 16-18%
SFO1-6 need 28-21%
CN1-2 need 23.2%
SCN1-17 need 13.1-25%
Clarification on the last figures. The current maximum difference between A and B scales, in per centage terms, is SCN1. This is because A scalers get a double increment rise there whereas B scalers don't. CN B scales remain 20-25% behind A scales until SCN10. From SCN 11 onwards, the difference reduces to be 13.1% at SCN 17. After the payrises and CN increment smoothing in CoS08, SCN 17 will be 3.2% behind A scales.
So in another 13 years when the most senior B scaler finally gets SCN17 he will be within 3.2% of the post cut A scales. That figure will still be 22.4% behind what A scales were in 1995.
