The rational part of me says that you should go with tfb's answer.
But my own laziness has led me to do a lot of stand-dev. If you'd like to experiment, put 5mL of Rodinal in per roll of film at 1:100 ratio.
Pre-soak your film for ~2min in water at developing temperature. Dump that and immediately put in your Rodinal.
I twist agitate for 1 min at the beginning, then another minute at the 30min mark. Develop for 60min total.
BTW, The phrase "Push" and "Rodinal" should never go together. If you're going to push Tri-X...go with your D76 or XTOL or Ilford's DD-X. I've never found the results all that pleasing when pushing film and developing w/ Rodinal, YMMV.
Stand development basics...With normal development, one uses more developer chemical than is actually needed and controls for the chemical reaction by keeping the developer cool (20C) and agitation under control. Note that it is possible to over develop by either increasing the temperature or increasing agitation while not compensating by diminishing time.
With Stand, one uses a tiny, tiny amount of developer, usually 1:100 ratio where the total volume of developer is 5mL per roll of film. Because this is highly experimental, you will find people that attempt developing with as little as 2.5mL or with ratios of 1:150, 1:200, etc. However, Rodinal recommends no less than 5mL per roll of film!
You are expecting that, at a microscopic level, the local area of developer near the highlight regions will exhaust while shadow regions will continue to develop. This is why agitation is kept to a minimum (or null) while time in developer is extended dramatically.
With Stand, we are expecting to exhaust all of the developer. Because of this, extra time in the tank past the 60min will not actually extend development. If you find that your negs are thin in your experiments, the only solution is to use more total volume of developer.
You're on your own warning:
Stand development should be considered highly experimental. The exact volumes, ratios, agitation, and time is not a standard. There is a good bit of consensus on starting with 5mL at 1:100 for 60min...but after that, anything you'll find online is usually a single person's routine. (For example, I've run across things like 'add 1mL for every stop pushed' or debates on pre soaking vs not)
Until you get a handle on how your film will come out with any given routine, please only use test shots or shots with little importance, as you may really screw up your film.
