The probability of receiving a Mid-Tech card is interesting, though, because those cards are needed so often: Over 2/3 of the vehicles need it during the PRO process and prior to it occupied 616 (~14.2 %) of the total 4340 applicable Pro Kit card slots (see the table under the header Pro Kit Formulas). If the applicable Pro Kit card slots' spread was even, it would occupy only 4340/36 ≈ 120 (~2.8 %) of the available slots. So the players' felt scarceness of the Mid-Tech card is built in the Pro Kit system, if the odds of receiving that card are not elevated by default. After the built-in Mid-Tech card bottleneck, Engine cards might turn out to be the next Pro Kit cards, that the players feel are not received according to a calculated even distribution..
