Except BBZ was using minutes played to get to his conclusion, which mitigates the unfair difference between a starter and a bench player.
Even on minutes level, a starter has the advantage of being relatively in form than a bench player who could be hot and cold, so I don't think even on a minute per goal level it is a fair comparison.
With that way, there is 0 point in comparing any stats:
1) if one player plays for Barca, and the other one for xx team=you can't compare them, since Barca creates way more shots
2) if both players play for Barca, but one is a starter and the other one is a sub player=you can't compare them since the other one will play hot and cold
3) basically, the only way to compare any stats is=compare 2 players from the same team, who play on the same position, and who are either both starters or subs, plus they need to play in the same matches against the same opponents so that we could have as many as possible equal variables.
With that way of thinking, squawka and all other stats sites make zero sense, since they are comparing players from different teams/different leagues all the time.
Anyway, let's go back to the world where we somehow need to compare players from different teams:
Paco, according to Squawka:
http://www.squawka.com/players/paco-alcacer/stats#total-goals-scored#valencia-cf#spanish-la-liga#23#season-2015/2016#176#all-matches#1-38#zone
-- 49 shots in total in La Liga 2015/16
-- 53% shots on target
-- 3,77 shots needed to score 1 goal
-- 13 goals from 49 shots
Munir, La Liga 2015/16:
-- 16 shots in total
-- 38% shots on target
-- 5,33 shots needed to score 1 goal
-- 3 goals from 16 shots
Also, Munir scored 8 goals last season, BUT:
-- only 3 goals in La liga
-- while he scored 5 goals in 5 Cdr matches
-- like 2 against Villanovense
-- 2 against Espanyol, 2nd leg, when the results from the first leg 4:1 (and 2:0 in the 2nd leg)
So, in majority of stats with minutes per goal, people are counting his stats from Cdr, which should be excluded.
Also, if you check Munir's stats, he played mostly at Nou Camp matches against Mickey Mouse teams, rarely in tougher matches.

-- scored 3 goals:
-- against Eibar, Getafe and Malaga
No matter how we look at stats, Paco just looks like a better player currently, scoring more in a crappy team like Valencia, from a lower amount of attempts.
Plus, he scored 6 goals for Spain NT in 13 appearances.
Wait, is there even debatable that Paco Alcacer is clearly better at no9 than Munir? That's pretty obvious, and that's coming from a guy who actually rated Munir even when he was playing badly.
Per minutes, not a whole lot of difference
So we basically wasted 30 M to get the same player we already had
What is done is done.. We loaned Munir and signed Alcacer.. A lot of people don't agree with that, specially now when Munir started to show some good games.. Barca decided they this way and we can't really do anything about it.. At the end of the season it will be shown if the decision was correct or not!
How exactly does that create an unfair difference?

Why are you excluding CDR?
That's where we played Munir last season
