Except in charged water and eatables or consumables like hygiene products or such things, energy gets divided for when requested for multiple receivers.
Water or other consumables is the medium for energy so when multiple people take charged water from same bottle they all recieve full energy. In other methods the energy is received simultaneously by all receivers so it gets divided.
You can either request more frequently say every 10 min or use multiple VKs to BOOST the healing to increase the energy.. or for most imp ECs you can request separately.
Being a VK user you may not require so many ECs
If you can share what these ECs relate to and what is written in those ECs maybe we can guode you more simplier or efficient ways.
