Haggle and OCR are at 1ms.
Not sure about finding item though, I'm pretty sure Abrosia / Valorsuite is able to find items in less than 50ms?
Well, Abrosia at 1sec(1000ms) haggle and OCR gives me approximately the same fastest speed as a 1ms haggle and OCR in Valorsuite.
Which means technically, with Abrosia on 1ms, i should be able to get sub 1second buy times. Maybe even 600ms buy times.
Edited:
Really needs to solve the problem of haggle offer too low.
Could have bought 3 more purple neggs :<
Abrosia is faster indeed, my buytimes with Abrosia can go as low as 650ms, with ValorSuite the lowest was around 1600ms.
