Gonzo, even RPI+0.5% means that your good self will hit the buffers in 26years time... and if you hit the heady heights of SATCO, then sooner still.
Furthermore although inflation is currently at 5.2% (driven mostly by fuel costs), most city boffins reckon next year infltion will struggle to exceed 2%, so we won't be getting any psychologically large rise (e.g 5.2%-current inflation)
