I bought 100 blanks from skylighter and their ematch kit. I made 100 ematches. I did it just to mess around. I never used them for dual deployment.
Half I used for ground testing and half used a motor lighters. I had three fail. One was my fault. That 97-98% success.
I do not make ematches because it is not worth the trouble.
I also bought 50 ematch heads to make my own. I soldered them on 50 wires. I used the same dip. I got 44 usable ematches. All were used for ground testing or motor lighters. Three failed to light. Success rate of 82%.
Making your own blanks is definitely not worth the effort. Lot of work with a lot of failures.
