Significantly bigger. It's not just all the space freed up by removing the camping (in 1994 there was camping in the Pyramid Field proper below the path, which is unthinkable now). But also an overlooked factor is the repositioning and reorientation of the stage, which freed up more of the field.
When you compare an aerial photo from then to now, it's very noticeable how much more space is available. And Elton absolutely did fill all of it.
I know this discussion isn't new ground (and I have absolutely no idea on numbers), but it definitely felt like a lot of people cleared off early this year.
The Pyramid post-Shania has to have been the most sparsely attended run on that stage possibly ever - we walked past not long after Burna Boy had finished and the crowd was taking up probably a third of the pit - everything I heard from people who were elsewhere was that it was pretty quiet, and even at Justice, where it actually was quite busy, we comfortably managed to get 3 off the barrier in line with the edge of the stage even with rocking up 15-20 mins beforehand
Deftones are not that expensive. Vilar de Mouros could book them and it's a much smaller festival. They were on the line-up for North Music Festival 2020, also a very small festival.
