18 dice and 7 Accuracy is a hit or more lost 22% of the rolls. That's excluding rerolls or explosions, I only ran the base stats. Let me check AnyDice for rerolls... How does <5% of less than 7 hits sound, with an 8/9 chance to lose hits?
Honestly though, all I want is that 10% chance or less at losing 1+ hits. At lower dicepools we're talking only roughly 1/3 of that chance of losing 2+ hits with that Accuracy, at higher dicepools it goes up to about half. Thanks to my tables, I can calculate the odds that replacing a Smartgun with a Laser Sight actually costs me a hit. It's a consequence and honestly, without skinlink it's something I'm willing to eat if it means I'm not restricted by the wire hanging from the gun.
If on the other hand I have to take that Accuracy hit because the smartgun won't work right at 20 meters without a wireless connection, I will take it even more but be snarling about it.
