Your spends would fall under two types: Base Spends and Boosted Spends.
Boosted Spends: When you spend at any boosted merchant, you earn extra rewards up to 2x (2 CYPR = $1 spent), 3x (3 CYPR = $1 Spent), or whatever multiplier is shown for that brand.
Base Spends: These are your regular spends (not on boosted merchants). Rewards for base spends are calculated at the end of each reward cycle based on your plan, total spend, and the base reward pool.
Note: The multiplier can change depending on how many people are spending at that merchant during the current cycle (epoch).
