I am not talking about a perched water table due to a relatively impervious layer, as in geology. Drainage in pots works differently, and a perched water table in a pot has nothing to do with how many holes are at the bottom. But if it works for you, I see no reason why you would need to change your method.
For anyone who wants to understand what I am eluding to, try this experiment and see for yourself:
