I've got two '93s (with ABS, of course) as well as an '84; and I use the same bleeder and fluid as you.

I always have a trouble light behind the clear plastic hose I use (i.e., the hose is between the bulb and my eyes) to drain the bleeder, so I can easily see the color and opacity of the fluid coming out of the caliper. It's always easy to see when the new fluid is coming out! And I've always found that I use (see next paragraph) more fluid than necessary -- but what the heck, it's worth it to be sure!

As a rule, I fill it with two quarts (~2,000 ml), and I just let them flow so that about 1/5 of the bottle's contents has flowed for each caliper (for the '93's ABS system), because these have only one bleeder for each front caliper; that will leave me 1/5 leftover after ~400 ml has flowed out of each bleeder. For the '84, because it has six bleeders, I use less fluid for each -- I estimate about 1/8 of the bottle, or 250 ml., as allocation for each bleeder!
