The problem with looking at the Reading trains in isolation is that it's not the "beyond Staines" element that really needs the capacity. The Reading trains pick up a lot of passengers (partly because they are the "fastest" services) at the likes of Feltham, Twickenham and Richmond who would otherwise have to go on other trains.I think the combined Windsor/Hounslow/Weybridge services need around 40 units. This ties in with remarks either earlier in this thread or elsewhere that there are still going to be plenty of 450s on the Reading line due to the requirement for 458/5s to supplement the 707s.
While there are a fair number of services to/from Reading that really need extra capacity some shoulder-peak ones don't (eg the 0742 from Reading which does one trip in the AM peak only) and the resources are probably better used on the Hounslow loop, in particular.
There is therefore logic in using 10-458 on all Reading trains. They have similar seating capacity to 8-450, but offer much more standing room to pick up the Feltham/Twickenham/Richmond traffic.
