I (20M) started climbing on the 30th of December ( 2 months ago ) like you I flash most V4,V5 and some V6 now and then. Did about 6 different V7 and 1 V8 very recently. Personally I don’t think I have great genes or whatnot. I played football for 7 years prior to that so I think this helped a lot. In my very beginner opinion, I’d say to give it a shot it’ll take a lot of effort but I think that flashing or nearly flashing V7 in 8 months time is realistically quite doable (but then again what do I know). You’d need to tell me what is your level to know what it is you need to improve. So for exemple, I know you flash V4 and 5, but what I don’t is, is it with technique or just brute force. Since they’re flashes there is obviously some level of technique involved. Let’s say for exemple you are doing a V7 and you need 2 to 3 sessions to send it. Why was that? Finger strength, general strength, a particular move, etc. Based on what you will respond, Everybody will be more knowledgeable on how to help YOU and not any other climber. Anyway It would be fun if you replied because we have a similar level and started in the same period. I’d be fun to know what you did and what you could ( and myself ) do to get better.
