This DCA approach e get how you go take apply am come even dey at loss more than certain market periods way if you go all in when the market done dip. Nah it's left for the investor to calculate himself and know what decision is best to take at every interval with market price. It gets when DCAing but by bit go be the best option and it gets when diving all in too go be the best too. But it's left for the investor to know these differences.
The problem is you can't accurately predict the market, if everyone could do that, then we will all be waiting for the best time to buy:), but can you boldly affirm the best point if you analyze one yourself? It's all assumption of how the market will turn out over time.. and yeah each investor decides what's best for him/her but it will be better if we don't make irrational decisions, sometimes you could think you find a perfect dip, go in all at once and the market still goes even more deeper

, no funds left to buy the the longer dip

, at the same time you might think you find a perfect spot and the market never gets there.. prediction could be somehow hard

BTW thank you for the laugh, your first sentence got me
