According to the rules, it must be like that, if you are disciplined even though it is not very routine, if divided on average you will get a fairly high price because the purchase of course varies in number every time.
For other people's opinions, I think it's enough to just listen if it's good, just adjust it to what you have learned, especially in this thread, both in terms of technique, pattern and duration. many have great experience and are also successful in implementing it.
