type flowing start outside the frame

Hello folks,

I have the following scenario:
I have a lets say 1280x720 composition and I would like to move multiple one line type layer from right to left, like a flowing stream. y position is random. Also I am able to move the whole type layer to start the animation with an offset I chose. I managed to work with this expression.

xPos= -(time- inPoint)*200 ; yPos = random(this_comp.height) ;
[ xPos+1580 , yPos ]

you notice the "+1580" in the last line? This is because I would like to have the text outside the frame when starting on the right side and scroll to left until it leaves the frame again. My question is whether this can also be written in expressions. This would be so helpful because I have different length of sentences I would like to type into the type layer, and it would be very time consuming evaluating the value of which it is not appearing in the frame.

I would be very thankful for any tips!

That number would be dependent on the font and its size that you use, I suggest that you replace the number with an Expression Control slider. It'll be very quick to discern the magic number for each line of text.
