that is not what you wrote

1) if the last two months can outsell the rest of the year = a short burst of sales can make up for the sales of the rest of the year

vs "on the contrary"

2) if the last two months can outsell the rest of the year = the sales in the Holiday period are mediated by the performance during the longer Else period

1) is not contrary to 2)

1) is not contrary to 2)

The issue is in the conclusions, the first one suggests that sales before the holiday period don't matter because the holiday sales good aka "Anything Can Happen". The second conclusion says the same thing but focuses on the total of the year aka "Consistency is Key". The second conclusion is in the contrary to the first one because it has a different connotation, a negative one, i.e you need good sales year round to benefit from the boost, vs the conclusion posed prior, a postive one, i.e the boost makes up for the rest of the year so bad sales don't matter.

Actually it is contrary because 1) states that a short burst can make up for the rest of the year. 2) states that the holiday months are dependant on the rest of the year. IE it is a long building slow burst that comes to a head in the holiday months and is completely dependent on the else months performance. Which is the opposite of a short burst making all the difference. Hope I cleared that up for you as it seemed to go way over your head.

Its not logical in the literal sense, which is how you are understanding it but its clear from the context that its a matter of conotation, the associative meaning of the phrase as opposed to its denotation, its literal meaning.
The two phrases literally mean the same thing i,e have the same denotation, but have different contrary connotations. 1) Focuses on the boost itself, while 2) focuses on the total that was brought down by the lower period.

Its not claim, counter claim its simply offering an alternative view point to the one that is common, boosts are great "Anything can Happen" but the baseline be sufficient as well "Consistency is key.

Its one whole logical block.

I am not arguing against the general point, which is pretty obvious

I am just saying that the argumentation is not logical

if the last two months can outsell the rest of the year it actually does mean that a short burst of sales can make up for the sales of the rest of the year

BUT it probably won't happen UNLESS the mediation of the performance during the longer Else period favors it.

Again,

2) is not contrary to 1)

2) is a condition of 1)

Amigo se echa en falta el punto. Tal vez otro idioma le ayudará a entender. 1) es contrario a 2) porque: 1) establece claramente que una ráfaga corta en unos pocos meses, en cualquier época del año puede hacer una diferencia. 2) establece claramente que la diferencia sólo se hace después de una larga y constante acumulación seguido por una gran explosión en los meses de vacaciones. Eso es contrario y no podría ser más clara. 2) no es un condiditon de 1) que está diciendo algo completamente diferente. ¿Comprendes mi amigo?

"establece claramente que una ráfaga corta en unos pocos meses, en cualquier época del año puede hacer una diferencia"

creo que no entiendes muy bien el ingles y habria que empezar por ahi... todo a lo largo del OP se habla de los dos ultimos meses del ano, y no "en cualquier época del año"

tambien te lo podria explicar en frances, holandes o rumano, ademas del ingles y el espanol, por si acaso

Yo sí puedo, señor. También la temporada de vacaciones es el punto de 2) y su punto principal. El punto de 1) indica un corto birst en pocos meses puede hacer una diferencia. Nunca especifica el momento en que. Lo cual es una de las razones por las que es contrario a 2).

1) est opposée à 2) parce que: 1) stipule clairement qu'une courte rafale dans quelques mois, à tout moment de l'année peut faire une différence. 2) indique clairement que la différence est qu'après une accumulation durable et constante suivie par une forte explosion dans les mois de vacances. C'est le contraire et ne pouvait pas être plus clair. 2) n'est pas un condiditon 1) ce qui veut dire quelque chose de complètement différent. Également la saison des vacances est le point de 2) et son principal argument. Le point 1) indique une courte BIRST dans quelques mois peut faire une différence. Il ne précise jamais le moment où. Qui est l'une des raisons pour lesquelles il est contraire à 2).

1) tegengesteld is aan 2), omdat: 1) stelt duidelijk dat een korte uitbarsting in een paar maanden, op elk moment van het jaar een verschil kan maken. 2) stelt duidelijk dat het verschil pas na een langdurige en stabiele accumulatie, gevolgd door een grote explosie in de vakantiemaanden. Dat is het tegenovergestelde en kon niet duidelijker zijn. 2) is geen requierment van 1), die iets heel anders zegt. Ook het vakantieseizoen is het punt 2) en zijn belangrijkste punt. Het punt van 1) staat een korte birst in een paar maanden kan een verschil maken. Het specificeert nooit de tijd wanneer. Dat is een van de redenen waarom het in strijd is met 2).

1) este opusă 2), deoarece: 1) prevede în mod clar că o scurtă explozie în câteva luni, în orice moment al anului poate face o diferenta. 2) prevede în mod clar că diferența este doar după o acumulare constantă și de durată, urmată de o explozie mare în lunile de vacanță. Care este opusul și nu poate fi mai clar. 2) nu este o condiție de 1), care este de a spune ceva complet diferit. De asemenea, sezonul de vacanta este punctul de 2) și punctul său principal. Punctul de 1) prevede o scurtă birst în câteva luni se poate face o diferență. Acesta nu specifică momentul în care. Care este unul dintre motivele pentru care este contrară 2).
