Ignoring the fact most stations refuse to do upgrades correctly:
If I have an Anytime Return from Taunton to Basingstoke (route Salisbury) and wish to upgrade the return portion to go via Reading on a Sunday when Super Off Peak is valid, is the upgrade as follows:
Taunton to Basingstoke (route Salisbury) Anytime Return £54.50
Taunton to Basingstoke (route Not London) Super Off Peak Return £59.20
Therefore difference is £4.70 and I pay half that at £2.35?
I know route change is only half but is fare and route change only half?
