Facts or myths about cycling??

Do you happen to know the name of these suckers?
Nitrobacter is the genous of aerobic bacteria that consumes ammonia.
Nitrosomonas is a genous of bacteria that can switch from aerobic respiration to anaerobic respiration.
Nitrosomonas europaea seems to be the most likely candidate for use in denitrification in aquariums. However, all members of Nitrosomonas could play a part. Slime buildup in the aquarium is typically Nitrosomonas.
 
And it's pointless for me to say the following without getting flamed:

Growth of Nitrobacter by dissimilatoric nitrate reduction

Abstract

Eight strains of the genus Nitrobacter grew under anaerobic conditions in the presence of nitrate. The growth was inhibited by nitrate concentrations above 0.5 mM. By a special culture technique inhibition caused by nitrite was abolished. Nitrate oxidizing cells grew in gas tight culture flasks as a biofilm on a gas-permeable silicone tubing. The biofilm allowed nitrate-reducing cells to grow at a low nitrite concentration. These cells grew either actively motile in the anaerobic medium, or in anaerobic zones of the biofilm. They produced nitrite and ammonia. Nitrogen balance calculations established a loss of inorganic nitrogen for 5 of 8 strains. This implies that nitrate-reducing cells produced furthermore volatile nitrogen compounds. N2O was detected by gas chromatography.

Im in the midst of cycling my 46g and I came across this website. Idk if its credible thats why Im asking about it. Here's the website: http://www.bluecrayfish.com/cycle.htm The part though that Im asking about is :

1. Run the aquarium at a high temperature, up in the low to mid eighties, Fahrenheit. Only do this if you have no pets in the aquarium which need lower temperatures. The higher temperature leads to faster cycling.
Bacteria will multiply faster and have increased metabolic rates at higher temperatures..but if you eliminate the fish, you are short-circuiting the very process you are attempting to establish.


2. Keep the tank only about 50-65% full. This creates a waterfall effect as the water leaves the filter, and when the water from the filter hits the surface of the aquarium water, there is a great deal of water turbulence, exposing more water to more air more quickly, and leading to increased oxygenation, and thus, faster cycling. Silly and incompatible with the purpose of the aquarium...which is to contain fish


3. Keep the aquarium light on 24 hours per day during cycling. Only do this if you have no pets in the aquarium which need less light, or which need darkness. The increased light leads to faster cycling.
Nonsense

4. Use as many air stones and air pumps as you have access to, which will fit in the aquarium. Keep them all running all the time. This leads to increased oxygenation, which leads to faster cycling. Oxygenation is required but the amount you suggest is unnecessary and incompatible with fish.

Only do this if you have no pets in the aquarium which need calm, or still water.

What do you guys think? Is he/she right? Thank you

Set up the tank in a normal manner compatible with the fish you desire to keep. Add the fish, add the bacteria and monitor ammonia, nitrite and nitrate.
