Want to accelerate towards Presto, How to acheive this?

Feb 1, 2019

So I am using Musescore 3 to write my impromptu. I have Musescore 2.3 on my other computer. Furthermore, that computer has the TempoChanges plugin. But I have also seen manual input of tempo marks used to accelerate or decelerate the piece. Of course, this is only roughly. But if I do it often enough such as by the 16th note, it wouldn't even be noticeable as abrupt changes. So I have a 10 measure introduction at Allegro, more specifically quarter note = 120 BPM. I am wanting to accelerate towards Presto as I get to the A section. I don't know yet how many measures I am going to have in between the first 10 measures of the introduction and the A section. But I want to get this accelerando effect in my playback. 

The easiest way I can think of doing it is emailing myself the score once I have reached the A section, opening the file on my other computer using Musescore 2.3 and adding the accelerando via the TempoChanges plugin, then saving it and emailing it to myself again and opening it in Musescore 3 and continue to write the impromptu, sending it to my other computer when I want to use ritardando and accelerando.  But, I don't know if this will actually work. It should because the TempoChanges plugin basically does what a manual adjustment of the tempo would do but automatically for any range of notes in the selection. 

The more labor intensive way would be for me to figure out how often to change the tempo, and then divide the overall tempo change by the number of times the tempo changes and manually put in all those tempos. Thing is, the TempoChanges plugin does put in fractional tempos. I don't know if you can manually input something like 130.5 BPM. And if I have to use fractional tempos, I might as well use the TempoChanges plugin.

So how should I go about this accelerando? Should I send it to my other computer and use the TempoChanges plugin using Musescore 2.3 and then send it back to my main computer and continue composing it using Musescore 3? Or should I put in all the tempos manually using Musescore 3? Or should I just watch the plugins on Musescore.org and wait until TempoChanges shows up on the list of 3.x compatible plugins and then install it and while I'm waiting, make note of where I want gradual tempo changes and the degree of change I want?
