Italy 100 liras 1990-1992 [solved]

The coin 100 liras KM# 96.2

in mintage section

shows

Note. Obviously the percentage is from wrongly described occurrence of lines and has nothing to do with frequency as it expected to be. This is not the case of this topic and in this post  onwards this nonsense will be omitted. 

It looks inconsistent. The years 1990 and 1991 have easily distinguished varieties of the same nature. Though the year 1990 is presented by one line and 1991 by two for business strike. 

Can the catalog be consistent by itself? It should be either 

- everywhere just one line for each year

or 

- the year 1990 should be splitted in the same way as 1991

1990 R  60 000 000 [nonsense not discussed] "99" in date with rounded tails

1990 R                        [nonsense not discussed] "99" in date with straight tails

If Numista wishes to hear an opinion, I'd rather recommend to divide the 1990 year business strike line. 

At the moment it is not consistent.

Poking @karrlot for opinion. :)

This one: N#2551  Yes, it is inconsistent and should be changed.

I split 1990 into two lines, one with rounded tail and one with straight tail.  

Looks like corrected.
