not every runner understand all the abbreviations used in the logs so ill try to explain them
im using this squirtle manip as an example:
[100] DVs FFFF :: 21/11/11/11/13  (offset: 32.905)	Player Len: 1, IGT: 15	blue_below_pal(hold)_gfskip_hop2_title0(S)_cont(A+A)  (base cost: 190)

[100] -> number of frames you have to wait after entering the rename screen. if its too low (<20 maybe) i would look for another manip since you need to hit start right after the A input and it can be quite hard to be both precise and fast enough 

DVs FFFF :: 21/11/11/11/13 -> stats, in order: attack, defense, speed, special. Its hexadecimal from 0 to 15 (F), F being the best 

(offset: 32.905) -> this is the offset you can use as a starting point. just put it into flowtimer then adjust it with your timing. These offset are pretty accurate for GBP/Gambatte, you will only need to adjust them slightly, but if you are using GBI they will be way too late (try to remove half a sec). 

Player Len: 1 -> for this manip to work, your trainer name need to be 1 char long

IGT: 15 -> you have to IGT track this manip and aim for frame 15. In this case (starter manips) entr only looked for manips that worked on 5 igt frames, so you can hit anything from 13 to 17 and it will still work
EDIT: the 5 igt window might not be true, need more info

blue_below_pal(hold)_gfskip_hop2_title0(S)_cont(A+A) -> this is really long to explain so im splittin it

blue -> this manips only works on blue version

below -> starters can be grabbed from multiple side. Charmander left/below, squirtle below, bulbasaur left/below/up. This is a squirtle manip so its always from below

pal -> how you should buffer palette
 nopal: nothing
 pal: tap any palette at the beginning
 pal(hold): hold a palette
 pal(ab): hold a palette then switch to another palette in the middle of the bios, when "GAME" is fully printed and its about to print 
  the B
 nopal(ab): hold a or b or start
 pal(rel): tap a palette, then switch to another palette (holding it) the same way as pal(ab)

gf -> how to buffer gamefreak screen
 gfskip (and then hop0): hold up-select-b
 gfskip (and then hop1+): hold start
 gfreset: hold a+b+start+select
 gfwait: buffer A when the last star disappear if the next input is hop0, if its hop(>0) instead just wait
 
hop ->
 hop1: hold a during the first hop
 hop2: same as hop1, but second hop
 hop3: same as hop2, but third hop (its the one after gengar attacks)
if you see hop1(reset) that means that insead of holding a during the first hop you hold a+b+select+start. it can be used during any hop

title-> how to buffer the pokemon title screen. the number indicate the amount of pokemon you have to wait before pressing something, 
 and (S) or (A) indicate what button you have to press (A or START), so:
 title0(S): clear the pokemon screen as soon as possible (first pokemon) by using START
 title1(A): clear the pokemon screen after 1 pokemon have scrolled by using A
 title0(scrollA): clear the pokemon screen while the first pokemon is scrolling away by using A. this is the trickiest one, i use audio cues
 as always if you see (reset) it means you have to soft reset with a+b+select+start

cont -> how to buffer the continue screen
 cont(A+A): hold A
 cont(S+A): hold Start then A when the second window appears. note that you wont hear the click like A+A. this type of continue is after a title(A)
 fsback(A+B): hold A through continue, but then backout with B
 fsback(S+B): hold Start through continue, but then backout with B
 mmback: hold b to get back to title screen

(base cost: 190)-> the amount of frames lost with this manip compared to the fastest (gfskip_hop0_title0_cont)

TID manips: 
the only difference its that we have no continue backout but instead we have options backout.
title0_opt(backout)_backout_title0_newgame -> start at pokemon screen, do an option backout (buffer down+a, then buffer start) then do another backout to title screen (buffer b), start at pokemon screen again then buffer A for new game
