Efficiency of sales strategy

This is something I thought of while I was watching the ENEOS Asia Professional Baseball Championship 2017 (I'm just happy that Japan won). In baseball, the batter might make a sacrifice hit when there is a runner with no out on the first base. After this, one run is scored even with a single hit. Then, it's a change after two withdrawals.

Recently, in high school baseball, there are fewer cases where the game pushes through without making the sacrifice hits when there is a runner with no out on the first base. This is because statistic data shows that the percentage of scoring a run does not change even if the game pulls through without the sacrifice hits.

Let's put this in terms of sales strategy. When comparing the percentage of a sales representative gaining figures by visiting door to door (push-type sales) and the percentage of making figures by advertising online and receiving orders from clients (pull-type sales), I think we can't always be certain that the former always has a higher percentage.

Perhaps using sacrifice hits as an example of sales strategy is inappropriate and meaningless, but I'm just wondering if there is any difference. If not, the latter would be easier not having to walk around. Plus, it's actually annoying, especially in patent offices and law offices to have clients come in without appointments, so I think visiting offices is not a good idea...

If you have any input on this, I'd love to hear them.
