The following will show how to calculate the total Production Points per hour for an example Epic rarity land plot with a Rare Totem and The Untamed title. The worker cards on the plot and their base PP contribution calculations are:
Three Max-Level Chaos Legion Regular Foil Commons - 1,000 PP each (base rate for max reg foil Common)
These cards provide a total base production rate of 29,500 PP / hour (1,500 Runi + 25,000 Beta Legendary + 3,000 for 3 max-level CL Commons).
Next we apply the boosts, which are additive. In this example we have the following boosts:
Runi - 100% boost
Epic rarity plot - 40% boost
Rare Totem - 25% boost
The Untamed Title - 50% boost
Therefore the total boost percentage is 215% (100 + 40 + 25 + 50), and the total PP boost is 29,500 * 2.15 = 63,425.
Finally, we add the base production to the boost production to get the total PP contributed by the workers on the plot every hour: 29,500 + 63,425 = 92,925 PP / hour.
The following will show how to calculate the total Production Points per hour for an example Common rarity land plot with a Common Totem and no Title or other boosts. The worker cards on the plot and their base PP contribution calculations are:
5 Max-Level Chaos Legion Regular Foil Rare cards - 1,100 PP each (base rate for max reg foil Rare)
These cards provide a total base production rate of 5,500 PP / hour. In this case, the only bonus is 10% from the Common totem which adds 550 PP (5,500 * 0.1), so the total PP / hour from this plot is 5,500 base + 550 bonus = 6,050 PP / hour.
Comments on the Examples
As you can see, there is a huge difference between a land plot with very rare cards like Runi and Alpha/Beta/Gold Foils plus other rare boosts such as Titles, Totems, and high rarity plots, as compared to plots with more common and cheaper cards and fewer boosts. This is intended as one of the main goals of the land expansion is to provide value and utility to the older edition cards which are no longer allowed in Modern.
It is important to keep in mind, though, that there are very, very few of those type of cards and those type of boosts, especially compared to the total number of land plots. Only a few percent of all 150k land plots will be able to have production numbers like those shown in Example 1 above, with the vast majority of land plots falling into something closer to Example 2.
Players who have Tracts or entire Regions of land will likely not have nearly enough older, gold foil, or other rare cards and boosts to fill the majority of their plots, so they will still need hundreds or even thousands of other worker cards to fill them. This is where the newer, more common cards like Chaos Legion rewards can provide the best value per dollar and allow players to make the most out of large amounts of land plots.
Also, please note that the cards used in the examples are assumed to be working on terrain types on which they receive neither a bonus or penalty to their base production rates.
