In this note, the further improvements to prior work in the area of geographical avoidance within the Tor network have been conducted, that aims to improve the security and performance of such systems. First, we propose a new approach to a prior method where the round-trip time from client to entry is directly measured rather than estimated. Secondly, we introduce a new system where we are able to extrapolate data collected from a comparatively small number of Tor circuits and apply it to other unmeasured connections. A dynamic threshold has been identified to partially compensate for inaccuracy and shifts up or down depending on the length of the circuit. The experimental results quantitively validate the effectiveness and efficiency of the new proposed system. The testbed produced in this work may prove useful to future research in the areas of traffic analysis, the Tor network, and geographical avoidance on the Internet.
