Is the amount of health I heal from a hacked pack related to Sombra's charge gain

Solution 1:

It would appear that her hacked health packs earn you ult charge rate the same way that Soldier 76 and Ana do. That is 1 point of ult charge for every 1 point of health healed.

• "Heroes gain 1 charge for every 1 point of self-healing done.
• Soldier: 76, Ana, and Sombra gain 1 charge for every 1 point of healing."

Solution 2:

As with any other character capable of healing others, the amount of ultimate charge gained depends on the amount of health healed.

Solution 3:

As of the patch on February 27, 2018, Sombra no longer gains any ultimate charge by having teammates collect hacked health packs.
