Timing Mathews Halon 6

I'm new the this forum and new to bow maintaince/tuning. Question on timing.

Just put new strings on my Halon 6. Peep and Nock in place. Everything looks level with rest. When I first put the string on...the cables were even in regards to the tiny circles on the cams. However, when I pull the bow on the draw board I notice that top cam hits the cable ever so slightly before the bottom cam. The bottom cam gap is 1mm at most. The best way to describe it is the top cam make firm contact with the cable while the bottom cam contact is not quite as firm.

My questions:
Does such a minuscle mismatch in timing affect arrow flight?
How would I correct this? If I twist the cable then the bottom cam overcorrects and is hitting too soon.

Thanks.
