Tyre pressures are always quoted as 'cold'. Ideally the car should have been stationary for more than 3 hours before you check the pressures. As Slowboy said - it just means that you prefer slightly different tyre pressures. No problem with that, but for consistancy, I would check pressures when the tyres are cold.

Question

I'm running a set of Toyo Proxies, 215/35/18.

I set the pressures at 34 front, 32 rear. I've found that there is about a 2psi difference if you check them when the tyres are hot or stone cold.

Originally I did them cold used them for a couple of weeks, then did them hot. The car feels much better when set like this (hot), a lot more confident and positive when charging into corners.

I've also messed around with the split too, any less than a 2psi difference front to rear ends up with a very light feeling rear end under heavy braking into corners.

Just after your views on the situation?

Just means you prefer them a little lower. A lot of people run 17"s which might need higher pressure to compensate for a softer sidewall than, say, SO3s. On 18"s I guess this is less of an issue.
