Hashrate inconsistency miner/pool

[pontiacg5]

So I diverted my 7870Ghz from bitcoins to try my hand at litecoins, right now I'm mining on ltc.kattare pool using CGminer. I run the two setx commands (sync objects/max alloc) then my bat file. Running tc 16384, 915 clock, 1250 mem, 1 thread, 256 work size, 2 lookup gap, and 19 as an intensity gets me around 380k in CGminer.

But, the GUI of the pool I picked shows my hashrate at 420k, what gives? It's shown it high for some time now, so I don't think it has to do with averages or anything. Running 19 as an intensity cripples the computer, is it possible the hashrate picks up once I walk away and leave the PC headless? It's a fairly decent rig, old FX-8150 and 16GB of low latency 1866 ram...

Should I trust the miner, or the pool?

Thanks for looking!

cgminer is the real hash rate. the pool calculate an approximation using nb of share and pool diff. most pool are a bit off most of the time up from what you really have but this always depend on luck so. cgminer is the real, the poll is the efficient hash rate a bite like the network hash rate is the time between block and diffculty, the network don't add miner hash it approximate what it should take to make the block at the actual rate.

The pool tries it best to guess your hash rate by how many shares you submit in a period of time.
And let me tell you this.. miners would rather see it a bit higher then a bit lower. Being higher by a tad
generally results in less questions ;-)
