A missing test, especially in the middle, doesn’t mean the cell can’t be used at that level. Any cell that can be used at a higher and lower level can be used at any level between those. The P28A can be used at anywhere from picoamps to 25A continuously and up to 35A as long as you don’t exceed its max temp spec.
Missing tests at the high end can mean they are beyond the cell’s rating but that’s what the ratings columns can be used for…to tell you if the missing test just wasn’t done or is at too high a current level.
