I'm sorry. I think I'm not grasping what you're saying. It happens sometimes - my English isn't always the best.
Is it something like this?
Event building: O, Canada!
chapter 1 | supplies/gold | 0.05% troop coll, 24 hrs | | | chapter 11 | seeds | 0.55% seed coll, 24 hrs | |
chapter 2 | supplies/gold | 0.10% troop coll, 24 hrs | | | chapter 12 | S1 | 0.60% S1 coll, 24 hrs | |
chapter 3 | T1 | 0.15% manu coll, 24 hrs | | | chapter 13 | S1 | 0.65% S1 coll, 24 hrs | |
chapter 4 | T1 | 0.20% manu coll, 24 hrs | | | chapter 14 | S2 | 0.70% S2 coll, 24 hrs | |
chapter 5 | T2 | 0.25% manu coll, 24 hrs | | | chapter 15 | S2 | 0.75% S2 coll, 24 hrs | |
chapter 6 | T2 | 0.30% manu coll, 24 hrs | | | chapter 16 | S3 | 0.80% S3 coll, 24 hrs | |
chapter 7 | T3 | 0.35% manu coll, 24 hrs | | | chapter 17 | S3 | 0.85% S3 coll, 24 hrs | |
chapter 8 | T3 | 0.40% manu coll, 24 hrs | | | chapter 18 | A1 | 0.90% A1 coll, 24 hrs | |
chapter 9 | mana | 0.45% mana coll, 24 hrs | | | chapter 19 | A2 | 0.95% A2 coll, 24 hrs | |
chapter 10 | mana | 0.50% mana coll, 24 hrs | | | | | | |
So the base percentage, and what it increases, is amplified per chapter. Then the percentages increase again as the building is evolved.
Did you intend the percentage to benefit various items each day? (like how the Genie gives out various items based on what the RNG can choose from)
Would the percentage compound if the collection occurs within 1 hour of the building being ready for pickup? (e.g. 0.05% becomes 0.055% at next pick up, if within 25 hours of previous pick up; 0.055% then becomes 0.060%, etc.) If so there would need to be a maximum yield - 10 days in a row would make a chapter 1 bldg equal to a chapter 2 bldg. That would have to be the upper limit. And as long as that was maintained, it would stay at the upper limit, so that when it is leveled up, no loss of benefit occurs.
Am I understanding the suggestion correctly?
