To clarify all this TP and Helper Power, let me lay down the law :P
TP = Total Power
Determined by the combination of all units in set 1
This means a few things
1. Affection is included in calculation
2. Ampys too
3. Equipment is not a part of TP
4. You can 'hide' your TP by only filling in the helper squad, typically showcasing a TP between 100-125k while the Helper squad remains unchanged
5. The game is glitchy and sometimes uses the most recent set of flower knights you used in a raid or mission as the 4 squads for TP calculations. eg. Your TP is around 380k, but for the event you created a specific set of flower knights to tackle a certain mission; an ally logging in may see your TP for the specific set of flower knight for the event which would most likely be lower than 380k
Onto Helper Squads
1. Affection is not calculated in helper power
2. Ampy is not calculated in helper power
3. Similarly to TP equipment plays no role in helper power
4. The helper units levels are restricted based your the highest level flower knight you have in possession
