On the other hand, there are 3 other categories of production: Improvements, Wonders, and Spaceship Parts. Assuming there is at least 1 shield in the Prod Box, one shield costs 2g for Improvements, and 4g for Wonders and SS Parts. This cost does not change no matter how many are bought at a time. Hence, IRB and IPRB terms are meaningless, unless someone just likes clicking the mouse and passing the time. The 2 terms that apply to these 3 categories are only the RB and PRB.
Actually, Incremental rush buying can apply to at least improvements. the key is your statement "Assuming thee is at least one shield in the Prod Box..." If there are NO shields in the box, there is a benefit to incremental rush buying. Rushing an item when you have no shields costs double the "normal" cost of rushing shields. Therefore improvements cost 2g/s *2 = 4g/shield, and so on. If you want to rush something without disbanding a unit or waiting a turn to put shields in the box, incremental rush buying can still save you money.
The first example is for rushing improvments. If you haven't built them already you can rush one of the cheap improvements (temple, barracks: 40s) for 4g/s*40s=160g, then rush the rest of the improvement at 2g/s. This can save considerable cash when rushing expensive improvements.
You can even use a IRB of improvements to help rushing units. Once you lose the 10s and 20s units and the cheapest thing to rush is a dip/musket at 30s, rushing the 30s unit with nothing in the box costs 210g. You can rush a temple or barracks for 160g, switch production to dip (which will take half the sheilds leaving you with 20s) and then buy the next 10s for 25g giving you 30s for a total of only 185g, then you IRB the unit from that point.
I guess a similar approach could be used for rushing wonders (if you don't have any caravans). rush an improvement, to start the prod box, then switch to the wonder and buy it.
These are limited cases, but I have definitely used both of the first two techniques.
