I tend to pitch lagers at the warm end and let it cool slowly. If I pitch on a cake, I always hit the low end.

The long and short of it is the yeast are the workhorses of beer. Everything you do is to create a happy environment and (flavorful )food for them to consume. The happier you make them the happier they will make you.

I don't do lagers so I cannot talk about that, but I hear that they take off slowly.

I do brew a lot of Belgians and that is a recipe for disaster. I did a brew and pitched it toward the high end of the temp range. The yeast took off and stayed hot for a long time before my fermentation chamber could cool it down. Total Fusel bomb. Also Belgian yeasts do not like to be cooled down after they start or you risk a stuck fermentation.

I guess it gets down to understanding the yeast you use and how it work best for you.

As a pro brewer friend of mine has said - his job isn't about grain, water and hops - it's about yeast ranching.

A majority of the things we do while brewing are about creating conditions that the yeast like. Yeast doesn't like temperature fluctuations or light. Pitching yeast into ferm temp wort is the best option. If you have temp control on your fermentation theoretically after pitching the yeast should be in a constant temperature - which make them happy.

Seems like everyone is saying the same thing here for the most part. And I would concur as well. I did 4 brews this past weekend and was only able to cool the wort down from the boiling tempt o about 78/80 degrees. My starters were conditioned in ferm chamber the morning of at 68 degrees. I pitched at the 78/80 degree temp w/ the 68 degree starters and saw yeast activity in 4-6 hours and the following day (yesterday) saw crazy blowoff happening where as I had to take out the airlock and replace w/ blow off tubes for two of the brews. The other two got close to blow off but managed ot stay within the carboy.
So to be honest this thread has shed some interesting light on on the process of how yeast works in the proof that I've seen with my 4 batches the past three days.
