I do use Int where it's easy loop counts, maths that doesn't require the precision etc. Have you tried implementing each item and then timing individually. Regards. Honest answer - no. Just by inspection of the game on the screen.  I was happy with the percieved frame rate. I implemented them Int first, then look up. Moving to INTs seems to make a visible difference - so I left it.  The look up - not so much as obvious, but I still left it as it didnt break anything. This raises the "AI" question again, where I was happy to delegate some of the thinking as this was for "fun" and not mission critical -- but I didnt test for sure, so dont have numbers. I'm working on Space Invaders that AI has done all the heavy lifting after I uploaded the MMBasic Manual - my Missile Command prog and told it what LCD panel it was using. One prompt and a runnable version stright to the 'Mite. Lots of tweaking still to do, but it worked first time with my working example to lean on. Colour me impressed.
