If 15 comes then 19 and then 4. Do you still put this in gap chart? If yes how? And do you start betting 19?

The numbers did not create a gap number.
 
If 15 came in then 4, that would create the gap number 19 and would show in
the gap chart as follows :
 
[table=,]
A,B,C
4,19,15,,1
[/table]
 
Note: It was 4 that created the gap number 19

If then 19 comes in next you will see from the gap chart that 19 is in the B
column where the gap numbers are placed and it will then also be placed in
the betting columns :
 
[table=,]
A,B,C
,19,
[/table]
 
If this was the start of a session the bet would be 4,19,15 and 19.

You will see that a 1 has been placed beside 4,19,15 this denotes at this stage
that it is in the lead and this won't change unless it is overtaken by another
gap line.
 
19 is a two unit bet and together with 4 and 15 the first bet will be 4 units.
