Hi @nisanharamati, thanks for the contributions. I don't think my constantly was a typo for continuously, but you did point out to me that the wording there is somewhat strange. I'm not sure about using continuously -- what are your thoughts?

[nisanharamati]

Hi @CamDavidsonPilon, I agree about continuously, it was the closest association I had last night when reading it for the first time, but it doesn't appear to convey the correct meaning either, does it?
How about progressively, increasingly or something along these lines?

[CamDavidsonPilon]

I like progressively. Do you want to make that change or shall I?

[nisanharamati]

I can make the change...
