n = 50
getPage || 1
id = getId || null
getIdIndex || 0

LastSyncPoint  = getPage * 50 + getIdIndex
api request /page/getPage[getIndex] ? inSync = true : inSync = false

offset = find(id)

find = getPage && getPage -1 && getPage + 1
if getPage == currPage
offset = indexOf currPage[id] - index Of getPage[id]
==========
add to db keep adding
1 table filled out
1 table from api
page stopped at
preload
10 image thumbnails

page1[0]
page2[0]
offset = where is page1[0].id now? page2? page3? keep going till you find it.

while you doing that filter out which ids already filled out


always check page 1
page1[0] page1[49]
last.page1[0] == curr.page1[0]?
if yes, continue where you left off
else
offset = id.indexOf(curr.page1[i])
