This is partially off-topic but I have to disagree
Evenly Spaced - it used to be that way
To Victoria in 2012 was xx:16 and xx:48 - 28 mins then 32
From Victoria it was xx:02 & xx:32 - exactly 30 mins gap
London Bridge was xx:07, xx:19, xx:37, xx:51
From LBG it was xx:03, xx:15, xx:33, xx:45
Both of which are fairly even and allows passengers to turn up and go
Yes in 2016 it is not that because of the diversion of half the London Bridge services to Blackfriars via Tulse Hill - one of the pains we have had to suffer to get the not improved timetable in 2018
The May 2018 proposal
As put forward at the public meeting in November and on the draft timetable was: -
Victoria every 30 minutes - still very even but journey time from 27 mins to 39 mins - a 40% increase
London Bridge - 10 mins then 20 mins which is very uneven and ruins the turn up and go aspect as you could have a 20 minute wait for the next one, 15 is the limit for turn up and go.
Reality is the plan doesn't appreciate that London Bridge and Victoria are completely different destinations as far as Redhill customers are concerned. You either go to one or the other not either.
So the concept of splitting the timetable evenly over both destinations is not valid and the proposed May 2018 timetable for Redhill is a terrible let down by GTR against their promises of improved services.
Would your need to specifically go to Victoria not reduce, given that trains to "London Bridge" (which will actually be cross-London Thameslink trains to Peterborough or Bedford) will serve Farringdon, for a dead easy interchange on to the Elizabeth Line for the West End, or for travelling directly to St Pancras?
Granted, if you wanted to specifically go to Victoria* and are fixated on getting a direct train (as opposed to taking the first train and changing at East Croydon if necessary) you are worse off, although an even 10 minute headway will better spread passenger loading (with better performance) for those who couldn't care less.
Otherwise, I'm struggling with how this could not be seen as a pretty pragmatic service offering for Redhill.
*District and Circle line connections also available at Blackfriars.
