Changing water during cycle

How often should you change water during an initial cycle? I've read that too much drags out the cycle. Will too little wipe out whatever might be on/in the LR? What's the most you'd want to let the ammonia reach before doing a water change?

once a week

even cycling you will have a better chance because the fresh water will help in growing new bacteria giving much needed oxygen and flushing out the bad elements
I test it daily, and sometimes end up doing water changes every other day of 25-50%. I just try and keep level around moderate and not at the extrememly high ranges.
When I cycled my tank I did a 10% change once a week. My cycle took about 2 - 3 weeks untill my levels zeroed out.
