* Regiomontanus's copy has no row labeled 1400, for the rows corresponding to 1360, 1400, and 1440 were incorrectly labeled 1440, 1480, and 1520.

Comparing this table with Table 21 we note that their corresponding entries for the motus are identical, whereas those for the time differ. The explanation is that the time in Table 21 refers to a year of 365d while that in Table 97 refers to a year of 365d 5;49,16h. However, as the motus is the increment in anomaly after a number of periods of anomaly in a certain number of years, both tables display the same entries for the same number of collected years.

Excess of revolution for the planets in expanded years: Tables 102 (Saturn), 103 (Jupiter), 104 (Mars), 105 (Venus), and 106 (Mercury)

Nu, f. 97v: In revolucionibus annorum expansorum Ed. 1526, f. 393r (Saturn: Tabula [symbol for Saturn] in revolutionibus annorum expansorum); f. 393r ( Jupiter); f. 393v (Mars); f. 393v (Venus); and f. 394r (Mercury)

The layout of this table is the same as that of Tables 97-101, but here the argument is the number of expanded years, from 1y to 40y: see Table 102. The presentation is the same as that for the mean motion of the planets in expanded years (Tables 22, 29, 36, 43, and 50). In Regiomontanus's copy all the information is gathered in a single table. The entries for 1y are 365d 5;49h (time) and 0;0° (motus) for Saturn,

Jupiter, Mars, and Venus; and 17d 14;34h (time) and 5,42;39° (motus) for Mercury. As was the case with the tables for collected years, the entries for time differ from those in Tables 22, 29, 36, 43, and 50, whereas the entries for the motus are identical in both sets of tables.
