As for serial order of the 1895s... it appears that the 5000 range was the start (around 2/1896), followed by the 6000 to 7900 range (into the third quarter 1896), with late 7000, 3000 & 4000's bring up the rear (to first part of 1897).
Within all the ranges you will find random dates that don't fit the pattern.
The date we use for the 1899 is the date sent to the ware house and the date shipped out of the plant. For the 1895 it is the date of receipt at Savage from Marlin and then the date shipped from Savage. So, the production order at Marlin might have been more in numeric order than the log shows.
