That is actually my main fear with learning thru CTFs. The sense of time and possibility is quite different. Almost like playing fast chess versus longer time chess games. It could be good practice but it very likely is detrimental if done too often.

IMO the hallmark of a "senior" vuln researcher is not only their ability to discover/exploit vulnerabilities in difficult targets, but, critically, their ability to effectively *invest and allocate resources*. Knowing when to sink more time/effort into an attack surface or difficult bug, and when you need to stop and *move on* is one of the hardest questions as a researcher, and you only develop that instinct through experience and hard-learned lessons.
