I love the simplicity of this. For you, Traindown may not offer much over what you have come up with. Here is what it would look like using the inline syntax

    @ 2020/07/15; #r:hpu; #w:3; #c:3; #d:1; push: 14; 18; 14; 14; 14; 30
    @ 2020/07/14; pull: 5; 5; 5; 5
    ...

Definitely not as human readable as yours for your use case. Thanks for sharing!
