I have used both my dope and Density Altitude in my "tribulations" and there was very little difference for ME. As Tim stated, probably because I am near sea level. I think JimmyJames brings up a valid point as to the value of all that dope we tend to record. I have an individual little book for each of my rifles that I record everything in; dope, load information, velocities, BC, scope parameters, and whatever happens during the session. I find it very useful as a reference more than a go-to to find dope for a particular day. But It has saved my butt a few times. Once my phone died and I had nothing but I did have enough dope recorded to scratch out some come-ups and so forth. And all of that other data came in handy when I purchased my new phone and had to enter all of the pertinent data again. Imagine not having a velocity for that particle sweet load that you had worked so diligently to find. I simply grabbed my "little book", entered the velocity, BC, scope height, etc., and was up and running in minutes. And I have data for all of the previous loads I had tried in that particular rifle as well. Even when I clean it (one of my rifles tends to go weird on me after about 150 or so rounds and then needs a cleaning). Now when I see my groups go south I check the "little book" and see how many rounds down the bore since the last time it got a good cleaning. Sure enough, it's in that range.
If I'm correct, JJ8 asked if there was an app to record all of that dope and I'm not sure there is? At least I've never seen one. Strelok and the like only let you enter your variables once. I replace weather variables at the beginning of each session and I'm not sure whether I can save the previous stuff or not?
