Why are Ecosia Bidding Strategies so wildly inconsistent?

Alright, fellow founders, I'm pulling my hair out over here. After trying to implement various Ecosia campaign optimization strategies, I'm noticing incredibly erratic behavior with the bidding. It's like the Ecosia ad platform decided to major in drama.

It genuinely feels like the Ecosia ad platform's bidding algorithms are having a mood swing every other day. I set a specific Ecosia bidding strategy (e.g., target CPA, maximize conversions), and one day it's performing great, the next it's burning budget for no conversions, then it rights itself, only to go haywire again. I've seen daily spend and CPA metrics jump by 200-300% on some days for the exact same campaign settings, then drop back down. It's almost like the system just decides to ignore the strategy for a bit.

Here's a snippet from my 'performance log' illustrating the chaos:

--- Ecosia Campaign Performance Log (Snippet) ---
Date       Spend      Conversions   CPA       Strategy
2023-10-20 $50.00     5             $10.00    Target CPA ($12)
2023-10-21 $48.50     4             $12.13    Target CPA ($12)
2023-10-22 $150.00    2             $75.00    Target CPA ($12)  <- WHOA!
2023-10-23 $60.00     6             $10.00    Target CPA ($12)
2023-10-24 $180.00    3             $60.00    Target CPA ($12)  <- AGAIN?!
2023-10-25 $55.00     5             $11.00    Target CPA ($12)

Has anyone else experienced such wild swings with Ecosia bidding strategies? Are there any hidden levers or specific settings to make the performance more predictable and less like a rollercoaster?
