Might touchy DJ J Mac
Are you a teacher?
Myself no, have I been in situations where I was teaching, yes. I also work at a university and throughout my time running around this campus, I've had a great many friends who have gone into education.
On the subject of education and teaching, let's take your proposition:
DJ A: 100 events per year and as such 100 chances to make and learn from mistakes
DJ B: 25 events per year and as such 25 chances to make and learn from mistakes
You propose that DJ A is superior because of the amount of times he has to practice in front of a live audience.
In your proposition you haven't mentioned anything about the events, but for the sake of argument, we'll say they are the same category of event, a wedding reception.
We know that no two receptions are the same because the bride, groom and guests are not the same, venue can be different, musical tastes can be different and the other vendors can be different.
With all the variables in this last statement alone (let's not even worry about the other myriad of variables out there), your proposition is in trouble.
Instead of going through the rest of this, let's just jump to the summary portion, shall we?
With so many variables being involved, it is easy to construct scenarios which will show DJ A or DJ B having more learning experiences than the other and some where they could end up having the same amount of experience.
Unless you can show concrete evidence that can stand up to scrutiny, your claim is not valid.
In simpler words, Cesar, your assumption about a DJ doing 100 events being better than a DJ doing 25 events is just that, an assumption.
