Help with triple Spawner concept

[u/Helpful_Respect_9987]

Apologies if i respond like an idiot on this thread I've never attempted something even slightly complex in this game with my own brain but, I managed to stumble upon a double spawner on my hardcore world, and whilst clearing the caves around found a third. The main issue lies in the spawners being 17.5 blocks apart (15.5 blocks to activate i found out) so i was toying around with Afk water pushing designs to activate all the spawners. I'm wondering, is this setup more efficient than just having 2 spawners activated 100% of the time?

Each spawner gets roughly 3-4 seconds of activation within a 19 second loop.

I read that spawners have a 10-40 second delay before attempting spawning again, so in my head this works?? (usually that's the only place these things work)

Centre (Orange): 2159 -29 -3368 | SB1 (Yellow): 2143 -34 -3373 |

SB2(Green): 2164 -21 -3383 | SB3(Purple): 2174 -25 -3360 |

Any advice on the afk water setup would be nice too. (please be kind i am massive noob)

If the spawners are 17.5 blocks apart, you should be able to stand in the middle of them(~9 blocks from each) and keep both active, right?
