Stocks should be weighted by Mkt Cap when determining RT Ranking, so that minuscule stocks don't unrealistically skew results. An example on 1/18/2010: an Industry 10-day RT Delta search shows the Mining (Uranium) Industry in position 4, mainly because URHNE (a tiny Uranium company) is up 93.3% for the day, catapulting this industry up from an RT Ranking of 168 to 4. The results are skewed and deceptive.
