An average 4th edition Street Sammy could fire an Ares Alpha on Full Auto Narrow Burst for 6P Base + 9DV burst fire, for a total of 15P damage. He loses 7 dice in the process on an unmodified gun. The target's defense test is unaffected. He deals -1 AP.
An average 5th edition Street Sammy can fire an Ares Alpha on Full Auto Burst for 11P base damage. He loses 6 dice in the process on an unmodified gun, and reduces the target's defense test by 9 dice. He deals -2 AP.
It certainly looks to me like you can do both at once in 5th edition. Yeah they got rid of Narrow Burst, but every gun has a much higher base DV. You really don't need bonus damage anymore as just about anything can one shot an opponent. Even the smallest palm pistol in 5th edition deals a base of 6P damage, equivalent to Assault Rifles and the largest Heavy Pistol in 4th edition.
Didn't You forget in your equation that in SR5 Dodge is REA & INT (not just REA) and that SR5 Armor is X1.5 compared to 4A ?

And skill caps doubled, while damage tracks didn't change. Let's say the Street Samurai example from each edition runs into the Professional Rating 5 grunts from each edition.
4th Edition Profession Rating 5 rolls Agility 7 + Firearms 5 + Smartlink 2 for 14 base dice. He fires his FN HAR on Full Auto Narrow Burst, losing 7 dice. He rolls 7 dice against the Street Samurai's Reaction 6. For some ridiculous reason the Street Samurai doesn't have the Dodge skill, which is a fatal mistake to make as a Street Sam in 4th edition, but if she did, she could choose to full defense and add up to 6 more dice to that test, giving her an easy dice pool advantage over her enemy, though she doesn't really need it. If the attack hits, she soaks a minimum of 16P with 4 body and 5 Ballistic Armor, so it does have a decent chance of killing her, but it will just as likely miss and do no damage.
5th Edition Profession Rating 5 rolls Agility 7 + Firearms 9 + Smartlink 2 for 18 base dice. He fires his Ares Alpha on Full Auto Burst, losing 5 dice. He rolls 13 dice against the Street Samurai's Reaction 7 + Intuition 3 - 9 from the burst, so he's got 1 dice. He full defenses out of necessity, adding his Willpower, and jumps up to 4 dice. Hell, he might as well edge it too, getting 5 exploding dice against his opponent's 13. This is all but guaranteed to hit him, at which point he soaks anywhere from 12P to 18P with Body 7 and Armor 11. 18 dice, So if he squeaks by with only 1 or 2 net hits on the defense test he might survive with a pile of Physical damage, but he's also way better equipped to soak than the 4th edition Sammy was. Using her stats of 4 Body and an Armor Vest (9 armor -2 AP), he'd be rolling 11 dice to soak, and could very easily die.
Despite adding a second attribute to defense tests and increasing armor, the increase of skill caps and damage values while condition boxes stayed the same makes 5th edition way more lethal. Adding the ability to fire Narrow bursts would be complete overkill, jumping an Ares Alpha from 11P to 20P. You mess up that defense test and you might as well not bother with the soak, because nothing short of a heavily armored troll survives that.
