cutting Flexwatt

[spidergecko]

Maybe this is a dumb question.

I decided to move to Flexwatt as my heating method. I wired my hatchling rack up. Everything is fine.

However, I thought I'd re-read the instructions on the "right" way to wire it and I seem to have misunderstood the proper way to cut the tape. It's the 4" wide type and the instructions say to cut through the black stripe. I cut it through the clear part (on an angle) between the black stripes. Is there a reason why this wouldn't be advisable?

Thanks.
