You are of course right.

In our internal calculation of the price of 1GB traffic we take
into consideration the average mix of traffic. We use a lower price
than reality in order to compensate for users who have more Israeli and
local traffic than international traffic. But of course this calculation
over-estimates the price by much for user who mainly have Israeli and
local downloads, and we don't have a solution for that for now (but
see below).

Currently we don't have a way to break down per-user traffic into
international, Israeli and local traffic volumes. We started to work on
a project in this regard, to break down the traffic to its components
in nearly real time (so the users will be able to track their traffic
continuously).
Regarding proxied traffic, HTTP proxied traffic is regretfully totally
negligible after we removed the transparent proxy (much time ago).
SMTP traffic through our mail servers is big, but comparing to the whole
traffic is negligible too.
