That is a great problem to have.
You want equal dollar weighted positions in each stock. So, you want them as close to fully equally weighted as possible. In other words, each stock…when fully invested should have about the same dollar amount invested whether that’s when its the initial position, or other one of the averagings.
Of course, as your account grows, you can ratchet that up very slowly over time (by gradually increasing the average dollar amount put in). But, keep in mind that also want cash set aside for when the market corrects severely and gives us even more opportunities for new picks and for fully averaging down on existing positions. But we don’t want to go over 3 equal dollar weighted positions in each stock (only exception being me authorizing a 4th position on one of our metals due to it not being a company that could ever go bankrupt and it’s a metal that has to be used).
